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.

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.
