The DPA-Switch™ IC family is a highly integrated solution for DC-DC conversion applications with 16-75 VDC input. DPA-Switch uses the same proven topology as TOPSwitch™, cost effectively integrating a power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. High performance features are enabled with three user configurable pins. Hysteretic thermal shutdown is also provided. In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tight temperature and absolute tolerance, to simplify design and reduce system cost.
LNK364 IC – Low Power Offline Switcher IC
The LNK364 incorporates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.
LNK419EG IC – Power Integrations – LED Driver Off Line Switcher IC
The LNK419EG dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability(LNK403-410). The single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacitor. The advanced primary-side control used by the LNK419EG device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits .LinkSwitch-PH incorporates a 725 V power FET, a continuous-mode PWM controller, a high-voltage switched current source for self biasing, frequency jittering, protection circuitry including cycle-by-cycle current limit and hysteretic thermal shutdown.
LNK304PN IC – Power Integrations – AC-DC Off Line Switcher IC
The LNK304PN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit Figure 1. Typical Buck Converter Application (See Application Examples Section for Other Circuit Configurations).and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or fly back converters. The fully integrated auto-restart circuit in the LNK304 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. A local supply provided by the IC allows use of a non-safety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters.
TNY288PG IC – Power Integrations Off Line Switcher IC
TNY288PG is also belongs to TinySwitch-4 Family from the manufacturer "Power Integrations". It is Energy-Efficient, Off-Line Switcher with Line Compensated Overload Power. It comes with following features:-
- Lowest System Cost with Enhanced Flexibility
- 725 V rated MOSFET
- Increases BV de-rating margin
- Line compensated overload power – no additional components
- Dramatically reduces max overload variation over universal input voltage range
- ±5% turn on UV threshold: line voltage sense with single external resistor
- Simple ON/OFF control, no loop compensation needed
- Selectable current limit through BP/M capacitor value
- Higher current limit extends peak power or, in open frame applications, maximum continuous power
- Lower current limit improves efficiency in enclosed adapters/ chargers
- Allows optimum TinySwitch™-4 choice by swapping devices with no other circuit redesign
- Tight I2 f parameter tolerance reduces system cost
- Maximizes MOSFET and magnetics utilization
- ON-time extension – extends low-line regulation range/hold-up time to reduce input bulk capacitance
- Self-biased: no bias winding or bias components
- Frequency jittering reduces EMI filter costs
- Pin-out simplifies heat sinking to the PCB
- SOURCE pins are electrically quiet for low EMI
TOP247YN IC – Power Integrations – Off Line Switcher IC
TOP247YN belongs to TOPSwitch-GX Family from the manufacturer "Power Integrations". It is with Extended Power, Design Flexiblity, EcoSmart & Integrated Off-line Switcher. TOPSwitch-GX uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to reduce system cost and improve design flexibility, performance and energy efficiency. Depending on package type, either 1 or 3 additional pins over the TOPSwitch standard DRAIN, SOURCE and CONTROL terminals allow the following functions: line sensing (OV/UV, line feed-forward/DCMAX reduction), accurate externally set current limit, remote ON/OFF, synchronization to an external lower frequency, and frequency selection (132 kHz/66 kHz). All package types provide the following transparent features: Soft-start, 132 kHz switching frequency (automatically reduced at light load), frequency jittering for lower EMI, wider DCMAX, hysteretic thermal shutdown, and larger creepage packages. In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tighter temperature and absolute tolerances to simplify design and optimize system cost.
TNY286PG IC – Power Integrations Off Line Switcher IC
TNY286PG belongs to TinySwitch-4 Family from the manufacturer "Power Integrations". It is Energy-Efficient, Off-Line Switcher with Line Compensated Overload Power. It comes with following features
TOP224YN IC – Power Integrations – Off Line Switcher IC
TOP224YN belongs to TOPSwitch-II Family from the manufacturer "Power Integration". It is three-Terminal Off-Line PWM Switch. Description The second generation TOPSwitch™-II family is more cost effective and provides several enhancements over the first generation TOPSwitch family. The TOPSwitch-II family extends the power range from 100W to 150W for 100/115/ 230 VAC input and from 50W to 90W for 85-265 VAC universal input. This brings TOPSwitch technology advantages to many new applications, i.e. TV, Monitor, Audio amplifiers, etc. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. The standard 8L PDIP package option reduces cost in lower power, high efficiency applications. The internal lead frame of this package uses six of its pins to transfer heat from the chip directly to the board, eliminating the cost of a heat sink. TOPSwitch incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC: power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.
