White LED Set-up Converter

The EC4503 is a current-mode and fixed frequency Boost converter with an integrated N-FET to drive white LEDs. The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and low feedback voltage reduce power loss and achieve high efficiency. Fa ●Wide Input Voltage from 2.7V to 6V●0.2V Reference Voltage●Fixed 1.5MHz Switching Frequency●PWM Brightness Control with Wide FrequencyRange of 100Hz to 100kHz●Build‐In Power MOSFET : 0.2Ω●Open‐LED Protection●Under‐Voltage Lockout Protection●Over‐Temperature Protection●<1mA Quiescent Current during S;
