SYNCHRONOUS BUCK CONTROLLER

A power management integrated circuit (IC) for high density, low output voltage converters, this secondary-side, synchronous pulse-width modulation (PWM) controller simplifies design of applications with multiple output power supplies, such as telecom and data communications modules, industrial supplies, computer, test and medical instrumentation and merchant power supplies.


The UCC2540 voltage-mode, synchronous buck controller is the first secondary-side control device with dual ±3A TrueDrive outputs to allow design of multiple power stages that can deliver currents up to 50 A and output voltages as low as 0.7 V.
