آی سی Ap3031KTR

ap3031 یک مبدل تقویت کننده DC/DC مبتنی بر سلف است .

General Description
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 4.7μH inductor and 0.47μF 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, TSOT

Applications
· 7' to 10' LCD Panels
