ISL97516

600kHz/1.2MHz PWM Step-Up Regulator

FN9261

Rev 6.00

March 28, 2014

The ISL97516 is a high frequency, high efficiency step-up

voltage regulator operated at constant frequency PWM mode.

With a 2.0A typical switch current limit and 200m MOSFET, it

can deliver over 90% efficiency. The selectable 600kHz and

1.2MHz allows smaller inductors and faster transient

response. An external compensation pin gives the user greater

flexibility in setting frequency compensation allowing for the

use of low ESR Ceramic output capacitors.

Features

• >90% Efficiency

• 2.0A, 200m Power MOSFET

• 2.3V to 5.5V Input

• 1.1*VIN to 25V Output

• 600kHz/1.2MHz Switching Frequency Selection

• Adjustable Soft-Start

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.

• Internal Thermal Protection

• 1.1mm Max Height 8 Ld MSOP Package

• Pb-free (RoHS compliant)

The ISL97516 is available in an 8 Ld MSOP package with a

maximum height of 1.1mm. The device is specified for

operation over the full -40°C to +85°C temperature range.

Applications

• TFT-LCD displays

• DSL modems

• PCMCIA cards

• Digital cameras

• GSM/CDMA phones

• Portable equipment

• Handheld devices
