RT9224 Datasheet (Richtek Technology) - 5-Bit Programmable Synchronous PWM Buck Converter Controller and Output Voltage Monitor

RT9224, 5-Bit Programmable Synchronous PWM Buck Converter Controller and Output Voltage Monitor

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, prov
