LM3405A: LM3405A

Part Number: LM3405A

Dear Sir,

We are looking for the development of a 1A Constant Current LED driver using similar IC's like LM3405A

Green LED
Forward Voltage: 3.0v - 3.6v
Typical Voltage: 3.1v
Typical Forward Current: 700mA
Qty:2 No's

Red LED
Forward Voltage: 2.0v - 2.6v
Typical Voltage: 2.1v
Typical Forward Current: 650ma-700mA
Qty:2 No's


All 4 LED's will be in Series, we want to supply 400mA to 500mA Constant Current using similar IC's like LM3405A.
I want the ON-OFF LED at 1HZ frequency and sometimes I want to turn on the LED Continuously.

Our Input Voltage: 16 V DC to 26 V DC
I don't want to use any heatsink on IC.
Please suggest a suitable IC for this application.


Regards
Murthy

  • Hi Murthy,

         I would strongly recommend the TPS92200D1 for you, this is a new device with good performance and which can support your power and dimming requirements. It can support from 4V to 30V supply voltage range and up to 1.5A output current and also support PWM dimming control.
