AP3064 Datasheet, PDF (1/20 Pages) Diodes Incorporated – FOUR-CHANNEL CURRENT SOURCE BOOST LED DRIVER

Description
AP3064
FOUR-CHANNEL CURRENT SOURCE BOOST LED DRIVER
Features
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 20mA to 220mA
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 SOIC-16, PSOP-16, DIP-16 and QFN-
4×4-16 packages.
