产品概述

The LM3404MA is a constant current Buck Regulator for high power LED driver, designed to deliver constant currents to high power LEDs. This regulator contains a high-side N-channel MOSFET switch with a current limit of 1.5A (typical) for step-down (buck) regulators. Hysteretic controlled on-time and an external resistor allow the converter output voltage to adjust as needed to deliver a constant current to series and series-parallel connected LED arrays of varying number and type. Some features of this product includes LED dimming using pulse width modulation (PWM), broken or open LED protection, low-power shutdown and thermal shutdown.
  • Cycle-by-cycle current limit
  • No control loop compensation required
  • Separate PWM dimming and low power shutdown
  • Supports all-ceramic output capacitors and capacitor-less outputs
  • Thermal shutdown protection
