Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external b€component count. V Applications n n Car Charger Battery Charger w` m Û y R Ñ w .g w w te o f o om c . ch Figure1.
