Description

The RT8249A/B/C is a dual-channel step-down, controller generating supply voltages for battery-powered systems. It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and two fixed 5V/3.3V linear regulators.

Key Features

  • A constant current ripple PWM control scheme operates without sense resistors and provides 100ns response to load transient
  • For maximizing power efficiency, the R
