FP6115B

FP6166 Dual 1.5MHz, 1A Synchronous Step-Down Regulator

General Description
The FP6166 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 FP6166 is packaged in MSOP-10L (EP) and DFN-10L (EP)
to reduce PCB space.
