EC4513 Datasheet, PDF (1/15 Pages) List of Unclassifed Manufacturers – White LED Step-Up Regulator

High Efficiency 1MHz, Step up Regulator
EC4513
General Description
Features
The EC4513 is the high power and high efficiency boost
converter with an integrated 30V FET ideal for LCD panel backlighting
applications. 30V output voltage allows for 8 high‐power LEDs in series,
and 3.5A inductor current limit allows for more LED strings connected in
parallel. The low 0.5V feedback voltage offers higher efficiency
in WLED driver applications. The wide input range from 2.7V to 21V
made EC4513 a perfect solution for various applications such as
LCD monitor and portable devices. The OVP pin monitors the
output voltage to protect IC during open load and FB pin short
circuit operations. The EC4513 provides the ALS pin to
simplify the interface to an ambient light sensor for automatic
dimming. The EC4513 is available in the thermally enhanced
DFN‐10 lead 3mmx3mm package.
