RT9224C
VRM 9.
0 Synchronous PWM Buck Converter Controller and Output Voltage Monitor
General Description
The RT9224C 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.
075V to 1.
85V by a 5-bit DAC which provides initial accuracy of ±1%.
The RT9224C drives two external N-Channel MOSFETs, providing high efficiency and eliminating the need for high cost P-Channel devices.
It senses the output current across the on-resistance of the N-Channel MOSFET and provides an adjustable current limit without external sense resistor.
The RT9224C monitors the output voltage and ...
