1.5MHz, 1A, High Efficiency Step-Down DC/DC Converter     CL1651


General Description


             CL1651 is a high-efficiency DC to DC step down switching regulator, capable of delivering up to1A output current. The CL1651 operates in a wide range input voltage from 2.7V to 5.5V making theIC ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz allows the useof small inductance value and low DCR inductors, thereby achieving higher efficiency.
