Introduction

AI Translation

The LM3402/HV are monolithic switching regulators designed to deliver constant currents to high power LEDs. Ideal for automotive, industrial, and general lighting applications, they contain a high - side Nchannel MOSFET switch with a current limit of 735 mA (typical) for step - down (Buck) regulators. Hysteretic control with controlled ON - time coupled with an external resistor allow the converter output voltage to adjust as needed to deliver a constant current to series and series - parallel connected arrays of LEDs of varying number and type, LED dimming by pulse width modulation (PWM), broken/open LED protection, low - power shutdown and thermal shutdown complete the feature set.
