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 1µA of current and can operate down to 2. 3V input supply. These features, along with 1. 2MHz switching frequency, make it an ideal device for portable equipment and TFT-LCD displays. The ISL97656 is available in a 10 Ld TDFN package with a maximum height of 1. 1mm. The device is specified for operation over the full -40°C to +85°C temperature range.
