Description of TPS3805H33DCKR
Specifically for DSPs and processor-based systems, the TPS3803 and TPS3805 series of supervisory circuits offer circuit initialization and time supervision. Unlike the TPS3803G15 device, which has an adjustable SENSE input that can be set by two external resistors, the TPS3803G15 has a fixed-sense threshold voltage VIT set by an internal voltage divider.
The TPS3805 devices offer a second adjustable SENSE input in addition to the fixed sense threshold monitored at VDD. If one of the two voltages falls below VIT, RESET is asserted.
RESET is asserted during power-on when supply voltage VDD rises above 0.8 V. The supervisory circuit then keeps the RESET switch active as long as VDD or SENSE are below the threshold voltage VIT. RESET is once more deasserted when VDD (SENSE) exceeds the threshold voltage VIT.
The product spectrum is made to work with supply voltages of 1.5 V, 3.3 V, and variable voltages. The components come in a 5-pin SC-70 package. The operating temperature range of the TPS3803 and TPS3805 devices is specified as 40?C to +85?C.

TNY280PN IC - TinySwitch?-III energy-efficient, off-line switcher with enhanced flexibility and extended power range that incorporates a 700V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable), and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability. The application includes chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, PC standby and other auxiliary supplies, DVD/PVR, and other low-power set-top decoders, supplies for appliances, industrial systems, and metering. ON/OFF control provides constant efficiency down to a very light load and it is ideal for mandatory CEC regulations and 1W PC standby requirements. Very low component count enhances reliability and enables a single-sided printed circuit board layout. High bandwidth provides fast turn-on with no overshoot and excellent transient load response.
