FN7370.1

White LED Boost Regulator With

Integrated Schottky Diode

Features

• Up to 6 LEDs in series

• 27V maximum output

• 2.7V to 5.5V input

The ISL97631 represents a high efficiency, constant

frequency PWM regulator with integrated boost diode and

FET. Designed for use in white LED driving applications, the

ISL97631 features efficiencies up to 85%. It operates at

1.35MHz switching frequency and operates from an input

voltage of between 2.7V and 5.5V. The maximum output

voltage of 27V enables the ISL97631 to drive up to 6 LEDs in

series. It is also possible to use the ISL97631 to drive LEDs

in series/parallel combination for applications requiring up to

15 LEDs.

• Up to 85% efficient

• 1.35MHz constant frequency

• Enable/PWM dimming control

• Pb-free plus anneal available (RoHS compliant)

Applications

• LED backlighting

• Cell phones

Available in the 6 Ld TSOT package, the ISL97631 offers

high efficiency, constant frequency operation. It is specified

for operation over the -40°C to +85°C ambient temperature

range.

• PDAs

• Handheld games

• MP3 players

• GPS
