Description
LM3404 1-A Constant Current Buck RegulatorThe LM3404 and LM3404HV devices are monolithic switching regulators designed to deliver constant currents to high power LEDs. Ideal for automotive, industrial, and general lighting applications, these devices contain a high side N channel MOSFET switch with a current limit of 1. 5 A (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
The LM3404 and LM3404HV devices are monolithic switching regulators designed to deliver constant currents to high power LEDs. Ideal for automotive, industrial, and general lighting applications, these devices contain a high-side N-channel MOSFET switch with a current limit of 1.5-A (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.
Features:
- Integrated 1-A MOSFET
- VIN Range 6 V to 42 V (LM3404)
- VIN Range 6 V to 75 V (LM3404HV)
- 1.2-A Output Current Overtemperature
- 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
- SOIC-8 Package, SO PowerPAD™-8 Package
