Description

  • Typical Application Circuit for LTC3121EDE 2.5V/4.2V to 175mA Single Li-Cell 3-LED Driver. The LTC3121 is a synchronous step-up DC/DC converter with true output disconnect and inrush current limiting. The 1.5A current limit along with the ability to program output voltages up to 15V makes the LTC3121 well suited for a variety of demanding applications. Once started, operation will continue with inputs down to 500mV, extending run time in many applications
