LM3406MH

The LM3406MH is monolithic switching regulator designed to deliver constant currents to high power LEDs. Ideal for automotive, industrial, and general lighting applications, it contains a high-side N-channel MOSFET switch with a current limit of 2.0A (typical) for step-down (Buck) regulators.

The features of LM3406MH can be summarized as:(1)Integrated 2.0A MOSFET; (2)VIN Range 6V to 42V ; (3)True average output current control; (4)1.7A Minimum Output Current Limit Over Temperature; (5)Cycle-by-Cycle Current Limit; (6)PWM Dimming with Dedicated Logic Input; (7)PWM Dimming with Power Input Voltage; (8)Simple Control Loop Compensation; (9)Low Power Shutdown; (10)Supports All-Ceramic Output Capacitors and Capacitor-less Outputs; (11)Thermal Shutdown Protection; (12)eTSSOP-14 Package.

The absolute maximum ratings of LM3406MH are:(1)VIN to GND:-0.3V to 45V; (2)VINS to GND:-0.3V to 45V; (3)VOUT to GND:-0.3V to 45V; (4)BOOT to GND:-0.3V to 59V; (5)SW to GND:-1.5V to 45V; (6)BOOT to VCC:-0.3V to 45V; (7)BOOT to SW:-0.3V to 14V; (8)VCC to GND:-0.3V to 14V; (9)DIM to GND:-0.3V to 7V; (10)COMP to GND:-0.3V to 7V; (11)CS to GND:-0.3V to 7V; (12)RON to GND:-0.3V to 7V; (13)Junction Temperature:150°C; (14)Storage Temp. Range:-65°C to 125°C; (15)ESD Rating:2kV; (16)Lead Temperature (Soldering,10sec):260°C; (17)Infrared/Convection Reflow (15sec):235°C.
