产品概述
The LM3492MH/NOPB is a 2-channel individual dimmable LED Driver with boost converter and fast current regulator. It is suitable for driving two individually dimmable LED strings with a maximum power of 15W and an output voltage of up to 65V. The boost converter employs a proprietary projected-on-time control method to give a fast transient response with no compensation required and a nearly constant switching frequency programmable from 200kHz to 1MHz. The application circuit is stable with ceramic capacitors and produces no audible noise on dimming. The programmable peak current limit and soft-start features reduce current surges at startup and an integrated 190mR, 3.9A N-channel MOSFET switch minimizes the solution size. The fast slew rate current regulator allows high frequency and narrow pulse width dimming signals to achieve a very high contrast ratio of 1000:1 at a dimming frequency of more than 3kHz. The LED current is programmable from 50 to 200mA by a single resistor.
