| Data Sheet WHITE LED STEP-UP CONVERTER General Description AP3031 The AP3031 is an inductor-based DC/DC boost converter designed to drive LED arrays. 1.4A switching current allows AP3031 to be used in different 7' to 10' LCD panel backlights 3*13 LED arrays typically . A constant frequency 1MHz PWM control scheme is employed in this IC, which means tiny external components can be used. Specifically, 1mm tall 4.7uH inductor and 0.47uF output capacitor for the typical application is sufficient. The over output voltage protection is equipped in AP3031, which protects the IC under open load condition. The AP3031 includes UVLO, soft-start, current limit and OTSD to protect the circuit. The AP3031 is available in standard SOT-23-6, TSOT23-6 and SOIC-8 packages. • Up to 92% Efficiency VIN=9V, IOUT=260mA • Up to 84% Efficiency VIN=5V, IOUT=260mA • Fast 1MHz Switching Frequency • Wide Input Voltage Range 2.7V to 16V • Low 200mV Feedback Voltage • Output Over Voltage Protection • Cycle by Cycle Current Limit 1.4A • Built-in Soft-start • Built-in Standby Mode to Achieve High Fre- quency PWM Dimming • Built-in Thermal Shutdown Function • Under Voltage Lockout • 7' to 10' LCD Panels • Digital Photo Frame • GPS Receiver • EPC • PDVD SOT-23-6 TSOT-23-6 SOIC-8 Figure Package Types of AP3031 BCD Semiconductor Manufacturing Limited 1 WHITE LED STEP-UP CONVERTER Pin Configuration K/KT Package SOT-23-6/TSOT-23-6 Pin 1 Mark SW 1 GND 2 4 CTRL Data Sheet AP3031 M Package SOIC-8 FB 1 GND 2 GND 3 8 CTRL 7 OV 6 GND 5 VIN Figure Pin Configuration of AP3031 Top View Pin Description Pin Number 6-Pin 8-Pin 2, 3, 6 Pin Name Function SW GND FB CTRL OV VIN Switch Pin. Connect external inductor and Schottky Ground Pin Voltage Feedback Pin. Reference voltage is 200mV Enable and Dimming Control Pin. Connect to a high input to enable the IC or a low input to disable the IC. If logic low time is more than about 0.7ms and then enable the IC, the AP3031 will soft start to protect system departments. If logic low time is less than about 0.7ms and then enable the IC, the AP3031 will hold on standby mode and start directly to achieve high frequency dimming Over-voltage Protection Input Pin. Connect to the output directly. On OVP condition, the output voltage will be clamped Ordering Information AP3031 Circuit Type Package K SOT-23-6 KT TSOT-23-6 M SOIC-8 G1 Green TR Tape and Reel Blank Tube Package SOT-23-6 TSOT-23-6 SOIC-8 Temperature Range -40 to 85oC AP3031KTR-G1 AP3031KTTR-G1 AP3031M-G1 AP3031MTR-G1 Marking ID GEC L1E 3031M-G1 3031M-G1 Packing Type Tape & Reel Tape & Reel Tube Tape & Reel BCD Semiconductor's Pb-free products, as designated with "G1" suffix in the part number, are RoHS compliant and green.
