The LM3404HVMA/NOPB is a constant current Buck Regulator for high power LED drivers. 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 regulator include LED dimming using pulse width modulation (PWM), broken or open LED protection, low-power shutdown and thermal shutdown.

• Integrated 1A MOSFET
• 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
• Green product and no Sb/Br
