Overview
UNISONIC TECHNOLOGIES CO.
, LTD L5100 LINEAR INTEGRATED CIRCUIT WHITE LED STEP-UP CONVERTER  DESCRIPTION The UTC L5100 is a STEP-UP DC/DC Converter and designed for driving white LEDs with a constant current.
It can drive several LEDs in series by a Li-Ion cell.
UTC L5100 switches at a high frequency 1.
2MHz, so it can allow the use of tiny external components.
The output capacitor can be as small as 0.
22μF; saving space and cost compare with alternative other solutions.
The low 95mV feedback voltage minimizes power loss in the current setting resistor can have better efficiency.
 FEATURES * Inherently Matched LED Current * High Efficiency: 83% Typical * Drives Up to Four LEDs from a 3.
2V Supply * Drives Up to Six LEDs from a 5V Supply * 36V Rugged Bipolar Switch * 1.
2MHz Switching Frequency * Uses Tiny 1mm Tall Inductors * Output Capacitor can be Small to only 0.
22μF  ORDERING INFORMATION Ordering Number L5100G-AF5-R Package SOT-25 Packing Tape Reel  MARKING www.
