GENERAL DESCRIPTION
FEATURES
Preliminary Datasheet AP3033 1.3A switching current allows AP3033 to be used in different 7' to 10' LCD panel backlights (3S8P LED arrays typically).● (VIN=9V, IOUT=160mA) 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 The over output voltage protection is equipped in AP3033, which protects the IC under open load condition.
● Under Voltage Lockout The AP3033 is available in standard TSOT-23-6 pack- age.
