General Description

The TPS5433xA family of devices are synchronous converters with an input-voltage range of 4.5 V to 28 V.

These devices include This device has an integrated low-side switching FET that eliminates the need for an external diode which reduces component count.

Efficiency is maximized through the integrated 128mΩ and 84-mΩ MOSFETs, low IQ and pulse skipping at light loads.
