1 / 7 page  UNISONIC TECHNOLOGIES CO., L5100 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 Copyright © 2005 Unisonic Technologies Co., QW-R103-024,A 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 allowing 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 SOT-25 1 2 3 4 5 SOT-363 1 *Pb-free plating product number: L5100L ORDERING INFORMATION Ordering Number Normal Lead Free Plating Package Packing L5100-AF5-R L5100L-AF5-R SOT-25 Tape Reel L5100-AN3-R L5100L-AN3-R SOT-363 Tape Reel |
