FP6162
1.5MHz, 1.5A Synchronous Step-Down Regulator
General Description
The FP6162 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
R
DS(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 FP6162 is packaged in MSOP-10L, DFN-10L and SOP-8L to reduce
PCB space.
