L3060

UNISONIC TECHNOLOGIES CO., LTD L3060 30V/500mA HIGH DIMMING RATIO LED CONSTANT CURRENT DRIVER  DESCRIPTION The UTC L3060 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the total LEDs chain voltage. The device provides an externally adjustable output current of up to 500mA for a single LED. A dedicated DIM pin accepts either a DC voltage (0.5V~2.5V) dimming or a wide range of pulsed dimming. Applying a voltage of 0.3V or lower to the DIM pin turns the output off and switches the device into a low current standby state. The UTC L3060 has a build-in power switch, based on different input voltage, UTC L3060 can drive several 1W or 2W LEDs.  FEATURES * 5V~30V input voltage range * Simple low parts count * Typical ±3% output current accuracy * Up to 500mA output current * Single DIM pin on/off and brightness control using DC voltage or PWM signal * High efficiency up to 97% * Adjustable constant LED current * Protection features: LED open-circuit protection LED short-circuit protection Internal thermal shutdown protection.  ORDERING INFORMATION Ordering Number Lead Free Halogen Free L3060L-AF5-R L3060G-AF5-R Package SOT-25 CMOS IC Packing Tape Reel www.unisonic.com.tw Copyright © 2017 Unisonic Technologies Co., Ltd 1 of 5 QW-R125-037.C L3060  MARKING CMOS IC  PIN CONFIGURATION VIN CS 54 123 SW GND DIM  PIN DESCRIPTION PIN NO. 1 2 3 4 5 ...
