TPS54900 Datasheet Programmable Four-channel Step-down DC/dc Converter

Manufacturer: Texas Instruments

Overview: TPS54900 (6,4 mm x 5,0 mm) PROGRAMMABLE FOURĆCHANNEL STEPĆDOWN DC/DC CONVERTER SLVS405 − OCTOBER.

General Description

The TPS54900 four-channel step-down converter uses voltage mode PWM control to provide four independently programmable output voltages.

Each regulated channel includes a high-side PMOSFET switch with a typical rDS(ON) of 0.8 Ω, which makes it suitable for high efficiency, low current applications.

Commands sent to the TPS54900 over the four-wire serial port programs the outputs independently or globally to supply voltages from 7.5 V to 13.1 V in 0.4-V increments.
