LESHAN RADIO COMPANY, LTD.
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 comparator.
The PFM controller allows the duty ratio to be automatically switched according to the load (light load: 50%, high output current: 75%), enabling products with a low ripple over a wide range, high efficiency, and high output current.
With the LR8301
