The LM3492QMHX/NOPB from Texas Instruments is an Automotive Grade, AEC Q100 Grade 1 Qualified 2-channel individual dimmable LED driver. It integrates a boost converter and a fast current regulator, making it suitable for backlight applications.
This device features a very wide input voltage range from 4.5 V to 65 V and programmable LED current from 50 mA to 200 mA. It supports a high contrast ratio of 1000:1 at dimming frequencies over 3 kHz. The boost converter operates with a nearly constant switching frequency programmable from 200 kHz to 1 MHz, requiring no loop compensation and remaining stable with low ESR capacitors.
The LM3492QMHX/NOPB includes two individual dimmable LED strings, capable of handling up to 65 V and a total of 15 W. It offers dynamic headroom control to maximize efficiency and features over-power protection with ±3% current accuracy. Supervisory functions include a precision enable pin and thermal shutdown protection.
Packaged in a 20-HTSSOP, this LED driver is designed for surface mount applications. It operates within a temperature range of -40°C to 125°C.
