SLVSCD5D – NOVEMBER 2014 – REVISED FEBRUARY 2016 TPS5433xA 4.5-V to 28-V Input, 3-A Output, Synchronous
Step-Down DC-DC Converter
1 Features 3 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. 1 Synchronous 128-mО© and 84-mО© MOSFETs for
3-A Continuous Output Current
TPS54335A: Internal 2-ms Soft-Start,
50-kHz to 1.5-MHz Adjustable Frequency
TPS54336A: Adjustable Soft-Start,
Fixed 340-kHz Frequency
Low 2-ВµA Shutdown, Quiescent Current
0.8-V Voltage Reference with В±0.8% Accuracy
