产品概述

The LM3407MY/NOPB is a constant current output floating buck Switching Converter designed to provide constant current to high power LEDs. The LM3407 has an integrated power N-MOSFET that makes the application solution compact and simple to implement. An external 1% thick-film resistor allows the converter output voltage to adjust as needed to deliver constant current within 10% accuracy to a serially connected LED string of varying number and type. Converter switching frequency is adjustable from 300kHz to 1MHz. The LM3407 features a dimming input to enable LED brightness control by pulse width modulation (PWM). Additionally, a separate enable pin allows for low power shutdown. Input UVLO and output open-circuit protection ensure a robust LED driver solution. The LM3407 is a constant current output floating buck switching converter with wide input voltage range and low feedback current sense reference voltage.
  • Accurate constant current output
  • Independent device enable (CMOS compatible) and PWM dimming control
  • Converter switching frequency adjustable from 300kHz to 1MHz
  • No external control loop compensation required
  • Supports ceramic and low ESR output capacitors
  • Input under-voltage lock out (UVLO)
  • Thermal shutdown protection
  • 0.1 to 0.9VIN Output voltage range
  • 150°C Junction temperature
  • 165°C Thermal shutdown threshold
  • 25°C Thermal shutdown hysteresis
