2A 4.5V-20V Input 500kHz Synchronous Step-Down Converter CXSD62641

CXSD62641 is a fully integrated, high– efficiency 2A synchronous rectified step-down converter. The CXSD62641 operates at high efficiency over a wide output current load
range.This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.The CXSD62641 requires a minimum number of readily available standard external components and is available in
an 6-pin SOT23 ROHS compliant package.
