ISL9220B Features

* synchronous PWM technology, maximizing power efficiency, thus minimizing charge time and heat. The 1.2MHz switching frequency allows use of small external inductors and capacitors. A simple charge current programming method is provided. External resistors program the fast charge and end-of-charge cu
