Applications LED Drivers Constant Current Sources Automotive Lighting General Illumination Industrial Lighting
DescriptionThe LM3404 and LM3404HV devices are monolithic
switching regulators designed to deliver constant
currentsto high power LEDs. Ideal for automotive,
industrial, and general lighting applications, these
devices containa 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
neededto delivera constant currentto series and
series-parallel connected LED arrays of varying
number and type. Some features are: LED dimming
using pulse width modulation (PWM), brokenor open
LED protection, low-power shutdown, and thermal
shutdown.
