Overview

Description

The ISL97656 is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 4. 0A, 120mΩ MOSFET, it can deliver up to 2A output current at over 90% efficiency. The selectable 640kHz and 1. 2MHz allows smaller inductors and faster transient response. An external compensation pin gives the user greater flexibility in setting frequency compensation allowing the use of low ESR Ceramic output capacitors. When shut down, it draws
