RT9224EC

The RT9224EC is designed as one kind of VRM 8.5 synchronous PWM buck converter controller and output voltage monitor. The regulated output voltage is digitally programmable from 1.05 V to 1.825 V by a 5-bit DAC which provides initial accuracy of +/- 1%. This device frives two external N-channel MOSFETs, providing high efficiency and eliminating the need for high cost P-channel devices.

Features of the RT9224EC are:(1)simple voltage mode PWM control with buck rectification;(2)+/- 1% DAC output voltage accuracy;(3)5-bit digital-to-analog output voltage range from 1.05 V to 1.825 V;(4)fast transient response ad excellent output voltage regulation;(5)fault protection for over-voltage and over-current;(6)power-good output voltage monitor.

The absolute maximum ratings of the RT9224EC can be summarized as:(1)Supply Voltage: +15 V;(2)Boot Voltage: +15 V;(3)Input, Output or I/O Voltage: GND -0.3V to VCC + 0.3V;(4)Storage Temperature Range: -65 °C to 150 °C;(5)Package Thermal Resistance SOP-20: 87°C/W.
