CAT37 Product details

DESCRIPTION
The CAT37 is a DC/DC step up converter that delivers a regulated output current. Operation at a constant switching frequency of 1.2MHz allows the device to be used with very small value external inductor and ceramic capacitors.

FEATURES
■ Low quiescent ground current (0.5mA typical)
■ Power efficiency over 80%
■ Compatible pinout with LT1937
■ Adjustable output current (up to 40mA)
■ High frequency 1.2MHz operation
■ Input voltage operation down to 2.5V
■ Low resistance (0.5Ω) power switch
■ Drives up to 4 White LEDs in series
■ Shutdown current less than 1µA
■ Load fault protection against open-circuits
■ Low value external components
■ Low profile 5-lead SOT23 (1mm max) and TDFN (0.8mm) package

APPLICATIONS
■ Color LCD and keypad backlighting
■ Cellular phones
■ Handheld terminals
■ Digital cameras
■ PDAs/Games
■ Portable MP3 players
