AP3064 Datasheet | Diodes Incorporated

Description The AP3064 is a high efficiency boost controller with 4-string current sources for driving WLED backlight. It operates over a wide input voltage range from 4.5V to 33V. The current of 4 strings are simply programmed from 20m A to 220m 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 AP3064 features cycle-by-cycle current limit, soft-start, under voltage lockout (UVLO) protection, programmable OVP, over temperature protection (OTP), open/short LED protection, VOUT short/Schottky diode open protection and Schottky Diode short-circuit protection. The AP3064 is available in SO-16 package.
