AP3033数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The AP3033 is an inductor-based DC/DC boost converter designed to drive °C arrays. 1.3A switching current allows AP3033 to be used in different 7' to 10' LCD panel backlights (3S8P °C 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 10μH inductor and 10μF output capacitor for the typical application is sufficient. The over output voltage protection is equipped in AP3033, which protects the IC under open load condition. The AP3033 includes UVLO, soft-start, standby mode, current limit and OTSD to protect the circuit.
