Description of TPS54332DDA
The TPS54332DDA is a non-synchronous buck converter with a low-RDS(on) high-side MOSFET that operates at 28 V and 3.5 A. An automatic pulse-skipping Eco-Mode feature is turned on to increase efficiency under light loads. Furthermore, the device can be used in battery-powered applications thanks to the 1-A shutdown supply current.
The external compensation calculations are made easier and the component count is decreased when using current mode control with internal slope compensation, which also permits the use of ceramic output capacitors.
The input under-voltage lockout’s hysteresis is controlled by a resistor divider. Voltage overshoots during startup and transient situations are restricted by an overvoltage transient protection circuit.
In the event of an overload condition, a cycle-by-cycle current limit system, frequency foldback, and thermal shutdown protect the device and the load. The 8-pin SOIC Power PADTM packaging for the TPS54332DDA is available.
