The RT9224 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 1.3V to 3.5V by a 5-bit DAC which provides initial accuracy of ±1%.

The RT9224 drives two external N-Channel MOSFETs, providing high efficiency and eliminating the need for high cost P-Channel devices.

Compatible with HIP6004B Simple Voltage-mode PWM Control with Buck Rectification ±1% DAC Output Voltage Accuracy 5-Bit Digital-to-Analog Output Voltage Range from 1.3 V to 3.5V Fast Transient Response and Excellent Output Voltage Regulation Fault Protection for Over-voltage and Over- Current Power-Good Output Voltage Monitor Fixed 200kHz Switching Frequency.
