ISL9108IRZ-T - Renesas Electronics

Description: ISL9107 and ISL9108 are 1. 6MHz synchronous step-down regulators with integrated power switches capable of delivering 1. 5A output current, which is ideal for powering low-voltage microprocessors in compact devices such as PDAs and cellular phones. These devices are optimized for generating low output voltages down to 0. 8V. The supply voltage range is from 2. 7V to 5. 5V allowing for the use of a single Li+ cell, three NiMH cells or a regulated 5V input. 1. 6MHz pulse-width modulation (PWM) switching frequ
