LM3402HV - 0.5-A Constant Current Buck Regulator

Download the LM3402HV datasheet PDF. This datasheet also covers the LM3402 variant, as both devices belong to the same 0.5-a constant current buck regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • 1 Integrated 0.5-A N-channel MOSFET.
  • VIN Range from 6 V to 42 V (LM3402).
