| Part Number | Description |
|---|---|
| RT9224C | VRM 9.0 Synchronous PWM Buck Converter Controller and Output Voltage Monitor |
| RT9224E | VRM 8.5 Synchronous PWM Buck Converter Controller and Output Voltage Monitor |
| RT9221 | PROGRAMMABLE SYNCHRONOUS PWM BUCK CONVERTER |
| RT9223 | 5 BIT PROGRAMMABLE SYNCHRONOUS PWM BUCK CONVERTER CONTROLLER |
| RT9201 | High Efficiency PWM Step-Down DC-DC Converter |
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.
