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.

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
