AP3064FNTR-G1

AP3064 Description 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.  Input Voltage Range: 4.5V to 33V  Drives up to 4 Strings in Parallel, 220mA per String  Programmable WLED Current from 20mA to 220mA  Adjustable Operating Frequency: 100kHz to 1MHz  String-to-string Current Matching Accuracy: ±1.5%  Built-in OCP, OTP, UVLO  External PWM Dimming  Open/Short LED Protection  Programmable Soft-start  Programmable OVP  Schottky Diode/Inductor Short-circuit Protection  VOUT Short/Schottky Diode Open Protection  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) 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, V OUT short/Schottky diode open protection and Schottky Diode short-circuit protection. The AP3064 is available in SOIC-16, PSOP-16, DIP-16 and QFN4×4-16 packages. Notes: Applications  LCD Monitor  LCD Display Module  LCD TV 1. No purposely added lead.
