General Description

The RT9224E is a high speed switching controller designed for use in Synchronous DC/DC buck converter for modern CPUs.

The regulated output voltage is digitally programmable from 1.05V to 1.825V by a 5-bit DAC which provides initial accuracy of ±1%.

The RT9224E drives two external N-Channel MOSFETs, providing high efficiency and eliminating the need for high cost P-Channel devices.

Key Features

Simple Voltage-Mode PWM Control with Buck Rectification ±1% DAC Output Voltage Accuracy 5-Bit Digital-to-Analog Output Voltage Range from 1.05V to 1.825V Fast Transient Response and Excellent Output Voltage Regulation Fault Protection for Over-Voltage and Over-Current Power-Good Output Voltage Monitor.
