Description
The AP3612 is a high efficiency boost controller with 12-string current sources for driving W°C backlight. It operates over a wide input voltage range from 4.5V to 33V. The current of 12 strings are simply programmed from 20mA to 75mA 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 °C protection, VOUT short protection and Schottky diode short-circuit protection.
