| Preliminary Datasheet WHITE LED STEP-UP CONVERTER General Description AP3033 The AP3033 is an inductor-based DC/DC boost con- • Up to 92% Efficiency verter designed to drive LED arrays. 1.3A switching VIN=9V, IOUT=160mA current allows AP3033 to be used in different 7' to 10' LCD panel backlights 3S8P LED arrays typically . Up to 88% Efficiency VIN=5V, IOUT=160mA A constant frequency 1MHz PWM control scheme is • Fast 1MHz Switching Frequency employed in this IC, which means tiny external com- • Wide Input Voltage Range 3V to 16V ponents can be used. Specifically, 1mm tall 10µH • Low 200mV Feedback Voltage inductor and 10µF output capacitor for the typical • Output Over Voltage Protection application is sufficient. • Cycle by Cycle Current Limit 1.3A • High Frequency PWM Dimming The over output voltage protection is equipped in AP3033, which protects the IC under open load condition. The AP3033 includes UVLO, soft-start, standby • • Built-in Soft-start Built-in Thermal Shutdown Function mode, current limit and OTSD to protect the circuit. • Under Voltage Lockout The AP3033 is available in standard TSOT-23-6 pack- age. • 7' to 10' LCD Panels • Digital Photo Frame • GPS Receiver • Netbook • PDVD TSOT-23-6 Figure Package Type of AP3033 BCD Semiconductor Manufacturing Limited WHITE LED STEP-UP CONVERTER Pin Configuration KT Package TSOT-23-6 Pin 1 Dot by Marking SW 1 GND 2 6 VIN 5 OV 4 CTRL Preliminary Datasheet AP3033 Figure Pin Configuration of AP3033 Top View Pin Description Pin Number Pin Name Function SW Switch Pin. Connect external inductor and Schottky GND Ground Pin FB 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 0.45ms and then enable the IC, the CTRL AP3033 will soft start to protect system departments.
