TPS54900 - Programmable Four-Channel Step-Down DC/DC Converter

Datasheet Summary

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.

Features

  • D Four Independent 100-mA Channels Programmable Over 4-Wire Serial Port D Converter Regulation Range: 7.5 V to 13.1 V in 400-mV Steps, Plus Unregulated Pass-Through Mode to Shunt VIN to any Output D Internally Compensated PWM Controller and Integrated PMOS Power Switches D Global and Per Channel Status Available Through Serial Port D External Synchronization of PWM With System Clock D Per Channel Current Limit and Global Thermal Shutdown D.
  • 40°C to 85°C Ambient Temperature Range.
