Description
The GM1937 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.
The device can drive two, three or four LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
Features
◆ High Efficiency: 84 Typical
◆ 36V internal Switch
◆ Fast 1.2MHz Switching Frequency
◆ Drives Up to three LEDs from a 2.8V Supply
◆ Drives Up to six LEDs from a 5V Supply
◆ External Matched LED Current
◆ Uses Tiny 1mm height inductor
◆ Requires Only 0.22 F Output Capacitor
◆ Low profile TSOT package
Application
Cellular Phones
PDA, Handheld Computers
Digital Cameras
MPS3 Players
GPS Receivers
