LM3464MH

The LM3464MH is a 4-channel high voltage current regulator that provides a simple solution for LED lighting applications. The device provides four individual current regulator channels and works in conjunction with external N-channel MOSFETs and sense resistors to give accurate driving current for every LED string.

The features of LM3464MH can be summarized as:(1)Wide input voltage range 12V-80V; (2)Dynamic Headroom Control ensures maximum efficiency; (3)4 output channels with individual current regulation; (4)High channel to channel accuracy; (5)Digital PWM/Analog dimming control interface; (6)Resistor programmable dimming frequency & minimum duty cycle (analog dimming mode); (7)Direct interface to thermal sensor; (8)Fault detection; (9)Over temperature protection; (10)Thermal shutdown; (11)Under voltage lockout; (12)Thermal enhanced eTSSOP-28 package.

The absolute maximum ratings of LM3464MH are:(1)VIN to GND:-0.3V to 100V; (2)DR1, DR2, DR3, DR4 to GND:-0.3V to 100V; (3)EN to GND:-0.3V to 5.5V; (4)All other inputs to GND:-0.3V to 7V; (5)ESD Rating,Human Body Model:±2 kV; (6)Storage Temperature Range:-65°C to + 150°C; (7)Junction Temperature (TJ):+ 150°C; (8)Supply Voltage Range (VIN):12V to 80V; (9)Junction Temperature Range (TJ):-40°C to + 125°C; (10)Thermal Resistance (JA):33.5°C/W; (11)Thermal Resistance (JC):6°C/W.
