LM3402/LM3402HV Constant Current Buck Regulators

Texas Instruments LM3402/LM3402HV Constant Current Buck Regulators 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 N-channel MOSFET switch with a current limit of 735mA for step-down (Buck) regulators. Hysteretic control with controlled on-time is coupled with an external resistor. This allows the converter output voltage to adjust as needed to deliver a constant current to series and series - parallel-connected arrays of LEDs. They can be of varying number and type, LED dimming by pulse width modulation (PWM) or broken/open LED protection. Low-power shutdown and thermal shutdown complete the feature set available with this device.
