Solar Lamp Using PR4403
The PR4403 LED driver is designed to provide a reliable solution for driving LEDs with a maximum current of 40mA. Its enhanced functionality over the PR4402 includes the LS input, which offers a convenient method to control the LED state. When the LS input is driven low, it triggers the driver to turn the LED on, allowing for straightforward integration into various applications where LED status indication is required.
The PR4403 operates efficiently, ensuring that the LED receives a consistent current regardless of variations in supply voltage or LED forward voltage. This stability is critical for applications where precise brightness levels are necessary. The device is suitable for use in consumer electronics, automotive lighting, and industrial indicators.
In terms of pin configuration, the PR4403 typically includes power supply pins, ground connections, and the LS control input. The device may also have additional pins for feedback or dimming control, depending on the specific application requirements.
Overall, the PR4403 LED driver combines simplicity and functionality, making it an ideal choice for designers looking to implement LED lighting solutions with minimal complexity while ensuring optimal performance.The PR4403 is an enhanced cousin of the PR4402 40mA LED driver. It has an extra input called LS which can be taken low to turn the LED on. This makes it v.. 🔗 External reference
