The LM3402HVMR/NOPB(购买请点击) are monolithic switching regulators designedto deliver constant currents to high power LEDs. Idealfor automotive, industrial, and general lighting applications,they contain a high-side N-channel MOSFET switch with aurrent limit of 735 mA (typical) for step-down (Buck) regulators.Hysteretic control with controlled on-time coupled withan external resistor allow the converter output voltage to adjustas needed to deliver a constant current to series andseries - parallel connected arrays of LEDs of varying numberand typeLM3402HVMR/NOPB(购买请点击), LED dimming by pulse width modulation (PWM),broken/open LED protection, low-power shutdown and thermalshutdown complete the feature set.
