FP6160 1.5MHz, 600mA Synchronous Step-Down Regulator 

General Description
The FP6160B 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. LowRDS (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 FP6160B is packaged in SOT23-5L, and TSOT23-5L to reduce PCB space.
