FP6172 1MHz, 2A Synchronous Step-Down Regulator

General Description

Download

The FP6172 is a high efficiency current mode synchronous buck PWM DC-DC regulator. The internal generated 0.8V 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 FP6172 is packaged in SOP-8L to reduce PCB space.
