General Description
The FP6167 is a high efficiency current mode dual synchronous buck PWM DC-DC regulator. The internal generated 0.6V precision feedback reference voltage is designed for low output voltage. Low RDS(ON) synchronous switch dramatically reduces conduction loss. To extend battery life for portable application, 100% duty cycle is supported for low-dropout operation. Shutdown mode also helps saving the current consumption. The FP6167 is packaged in DFN-12L to reduce PCB space.
