FP6160-1.5MHz,600mA Synchronous Step-Down Regulator
General Description
Download
 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. 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 FP6160 is packaged in SOT23-5L, and TSOT23-5L to reduce PCB space.
