Introduction
The CE9908 is a CMOS step-up

Low voltage operation: Oscillation start

switching DC/DC converter that mainly consists of a reference voltage source, an oscillator, and a comparator. The CE9908 allows the duty ratio to be automatically switched according to the load (light load: 66%, high output current: 78%), enabling products with a
