SLUS973A – OCTOBER 2009 – REVISED NOVEMBER 2016 TPS5429x 1.5-A and 2.5-A Dual, Fully-Synchronous
Buck Converter With Integrated MOSFET
1 Features 3 Description The TPS54290, TPS54291, and TPS54292 devices
are dual-output, fully synchronous buck converters
capable of supporting applications with a minimal
number of external components. It operates from a
4.5-V to 18-V input supply voltage, and supports
output voltages as low as 0.8 V and as high as 90%
of the input voltage. 1 4.5-V to 18-V Input Range
Output Voltage Range 0.8 V to DMAX Г— VIN
Fully Integrated Dual Buck: 1.5 A and 2.5 A
