1 Watt Led Driver Ic

Led driver ic s high brightness led drivers are integrated circuits that are optimized to efficiently drive strings of high brightness leds.

1 watt led driver ic.

Integrated driver mosfet 59 led drivers. Load drivers relay drivers 28 motor drivers brushed 20 motor drivers brushless 85 motor drivers stepper 61 voltage references supervisors. The input mains 220v or 120v ac is half wave repaired by d1 and c1. The simple 1 watt led driver circuit buck converter presents approximately 90 efficiency.

Secondly a 1 watt led would require anywhere between 20 to 350 ma of current for operating 100 ma being a respectable current for driving these light machines. Voltage references 29 voltage supervisors 45 power modules. A 1 watt led needs minimum 3 volts supply which is double the above cell rating. I was searching for a led driver that can also act as dimmer for my 10 watts leds and found the pt4115 ic which is kind of interesting.

A 1 watt led is relatively huge when compared to a 1 5 v aaa cell source. The driver part works by using a cmos hex inverter cd4069 in which a couple of of the inverters structure an oscillator with 31 duty cycle at approximately 11 5 khz or 66us off time as well as 21us on time for the mosfet switch. Ac dc led drivers 48 dc dc led drivers 35 linear led drivers 52 motor drivers. Maxim s continually expanding portfolio includes products covering the full range of efficient switch mode topologies step down step up sepic as well as some linear led drivers.
