RT8800A General Purpose 3-Phase PWM Controller for High-Density Power Supply General Description The RT8800A is a general-purposed multi-phase synchronous buck controller dedicating for high power density applications. The RT8800A operates with 2 or 3 synchronous buck switching stages in interleaved phase set automatically. The multiphase architecture provides high output current while maintaining low power dissipation www.DataSheet4U.com on power devices and low stress on input and output capacitors. The output voltage is precisely regulated to the external reference voltage at PI pin. The RT8800A can provide Intel® VRD10.x or AMD® K8 compliant output voltage when companioned with DAC generator RT9401A/B.
