AP3612 Datasheet | BCD Semiconductor

Preliminary Datasheet Boost Type LED Driver with 12-Channel Current Source General Description The AP3612 is a high efficiency boost controller with 12-string current sources for driving WLED backlight. It operates over a wide input voltage range from 4.5V to 33V. The current of 12 strings are simply programmed from 20m A to 75m A with an external resistor. The current matching between each string is 1.5% (Typ). Its operating frequency can be adjusted from 0.1MHz to 1MHz. The AP3612 Features Cycle-by-cycle Current Limit, Soft Start, Under Voltage Lock Out (UVLO) protection, programmable OVP, Over Temperature Protection (OTP), open/short LED protection, VOUT short protection and Schottky diode short-circuit protection. The AP3612 is available in HSOP-28 and SOIC-24 packages.
