Led Driver Pr4403

Pins 3 and 6 of the device must be connected together and together form the output of the circuit. The PR4403 is available in an SO-8 package with a lead pitch of 1.27 mm. Deep discharge of the battery cell is prevented as the PR4403 shuts off the driver when the supply voltage drops to less than 850mV. Name Comment   Captcha Question: What is 1 + 2 ?

In contrast to similar designs, here we can make do with a single 1.2 V cell.

The new PR4403 drives and controls white LEDs out of one single battery charged by solar cells. Applications for the PR4403 are solar garden lamps as well as house number lights, decoration lights and road markers powered by solar cells. An additional photodiode becomes dispensable. Let's call that 50-55 EB last year.

Very clever. The other components are a 1N4148 diode (or a Schottky 1N5819) and a 4.7µH choke.

When darkness falls so does the voltage across the solar module: when it is below a threshold value the PR4403 switches on.

Your existing password has not been changed. Yes, there's more flash being made but you're talking hard drive replacement... Furthermore, the PR4403 prevents depth discharge that extends the life time especially from NiMH-batteries. This makes it very easy to build an automatic LED lamp using a rechargeable battery and a solar module.

The value of the external inductor defines the LED current. It uses the connected solar cells to detect daylight. Michael Greer Load More Your name or email address: Do you already have an account?
