1.0A恒流降压稳压器用于驱动高功率LED 1.0A Constant Current Buck Regulator for Driving High Power LEDs
The from Texas Instruments is a 1A constant current buck regulator for driving high power LEDs in 8 pin SO PowerPAD package. This monolithic switching regulator is designed to deliver constant currents to high power LEDs. This device contains a high side N-channel MOSFET switch with a current limit of 1.5A typical for step-down buck regulators. The LM3404HV device is a buck regulator with a wide input voltage range, low voltage reference and a fast output enable and disable function. 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 are: LED dimming using pulse width modulation PWM, broken or open LED protection, low-power shutdown and thermal shutdown.
