Integrated 4A Switch PWM Step-Up

Regulator

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 makes 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.
