Product Overview

The LT1937ES5#TRMPBF 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. The LT1937 switches at 1.2MHz, allowing the use of tiny external components. The output capacitor can be as small as 0.22µF, saving space. A low 95mV feedback voltage minimizes power loss in the current setting resistor for better efficiency.
  • Inherently matched LED current
  • 84% Typical High efficiency
  • 36V Rugged bipolar switch
  • Requires only 0.22µF output capacitor

Applications
