FP6161
1.5MHz, 1A Synchronous Step-Down Regulator
General Description
The FP6161 is a high efficiency current mode 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 FP6161 is packaged in DFN-6L, SOT23-5L, and TSOT23-5L to reduce
PCB space.
