LM3492MH

The LM3492MH  integrates a boost converter and a two-channel current regulator to implement a high efficient and cost effective LED driver for driving two individually dimmable LED strings with a maximum power of 15W and an output voltage of up to 65V. It is available in the thermally enhanced eTSSOP-20 package.

The features of LM3492MH can be summarized as:(1)Very wide input voltage ranged from 4.5V-65V; (2)Programmable soft-start; (3)No loop compensation required; (4)Stable with ceramic and other low ESR capacitors with no audible noise; (5)Nearly constant switching frequency programmable from 200 kHz to 1MHz.

The absolute maximum ratings of LM3492MH are:(1)VIN, RT, VOUT to GND:-0.3V to 67V; (2)SW to GND:-0.3V to 67V; (3)SW to GND (Transient):-2V (<100 ns); (4)ILIM to GND:-0.3V to 0.3V; (5)FB to GND:-0.3V to 5V; (6)COMM, DIM1, DIM2, to GND:-0.3V to 6V; (7)ESD Rating, Human Body Model:±2kV; (8)Storage Temperature Range:-65°C to +150°C; (9)JunctionTemperature (TJ):150°C; (10)Supply Voltage (VIN):4.5V to 65V; (11)Operation Temperature Range (TA):-40°C to +125°C; (12)Thermal Resistance (JA) :32.7°C/W.
