LR8301 Description
SMALL PACKAGE PFM CONTROL STEP-UP DC/DC CONVERTER Introduction The LR8301 Series is a CMOS PFM-control step-up switching DC/DC converter that mainly consists of a reference voltage source, an oscillator, and a parator. The PFM controller allows the duty ratio to be automatically switched according to the load (light load: 50%, high output current:.
