TPS40200EVM-002

Оценочный модуль для несинхронного понижающего контроллера TPS40200.

The TPS40200EVM-002 is an evaluation module for TPS40200 non synchronous buck controller. It provides a resistor selected 3.3V output voltage that delivers up to 2.5A from a 24V input bus. The TPS40200 is a flexible non synchronous controller with a built in 200mA driver for P channel FETs. The evaluation module operates from a single supply and uses a single P channel power FET and schottky diode to produce a low cost buck converter. The part operates at a 200KHz clock frequency as determined by an external resistor and capacitor. The TPS40200EVM-002 is designed to operate with an 18V to 36V input and to produce a regulated 3.3V output with a load current from 0.125A to 2.5A. This module demonstrates using the TPS40200 in a typical buck converter application. The board sacrifices some layout density to provide ample test points for module evaluation. This evaluation module can be modified to support output voltages from 0.7V to 5V and above, by changing a single feedback resistor.
