| Preliminary Datasheet Boost Type LED Driver with 12-Channel Current Source AP3612 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 20mA to 75mA with an external resistor. The current matching between each string is 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. • Input Voltage Range 4.5V to 33V • Drives up to 12 Strings in Parallel, 75mA per String • Programmable WLED Current from 20mA to 75mA • Adjustable Operating Frequency 100kHz to 1MHz • String-to-string Current Matching Accuracy: • 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 • LCD Monitor • LCD Display Module • LCD TV HSOP-28 SOIC-24 Figure Package Types of AP3612 BCD Semiconductor Manufacturing Limited 1 Preliminary Datasheet Boost Type LED Driver with 12-Channel Current Source AP3612 Pin Configuration M28 Package HSOP-28 CH2 1 CH3 2 CH4 3 CH5 4 CH6 5 NC 6 GND 7 28 CH1 27 DIM 26 COMP 25 NC 24 STATUS 23 VIN 22 VCC CH7 8 CH8 9 CH9 10 CH10 11 CH11 12 ISET 13 CH12 14 21 NC 20 GND 19 OUT 18 CS 17 EN 16 RT 15 OVP M Package SOIC-24 CH7 1 CH8 2 CH9 3 CH10 4 CH11 5 ISET 6 CH12 7 OVP 8 RT 9 EN 10 CS 11 OUT 12 24 GND 23 CH6 22 CH5 21 CH4 20 CH3 19 CH2 18 CH1 17 DIM 16 COMP 15 STATUS 14 VIN 13 VCC Figure Pin Configuration of AP3612 Top View BCD Semiconductor Manufacturing Limited 2 Preliminary Datasheet Boost Type LED Driver with 12-Channel Current Source AP3612 Pin Description Pin Number HSOP-28 SOIC-24 28,1,2,3,4,5, 18,19,20,21, 22,23, 8,9,10,11,12 ,14 1, 2, 3, 4, 5, 7 Ordering Information AP3612 Circuit Type Package M28 HSOP-28 M SOIC-24 G1 Green Blank Tube Package HSOP-28 SOIC-24 Temperature Range -40 to 85°C AP3612M28-G1 AP3612M-G1 Marking ID AP3612M28-G1 AP3612M-G1 Packing Type Tube BCD Semiconductor's Pb-free products, as designated with "G1" suffix in the part number, are RoHS compliant and green.
