Posted on by pinout

Part Number: BP2832A

Function: Non-isolated Buck Offline LED Driver

Package: SOP-8 Pin Type

Manufacturer: BPS ( Bright Power Semiconductor )

Images:BP2832A datasheet

Description

The BP2832A is a high precision buck constant current LED driver. The device operates in critical
conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.
The BP2832A integrates a 500V power MOSFET.

With patent pending MOSFET driving technique, the operating current of the IC is very low. So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.

YX8019 PDF – Solar LED Driver – TO-94-4

Posted on by pinout

Part Number: YX8019

Function: Solar LED driver

Package: TO-94-4 Pin type

Manufacturer: ETC, Shiningic

Description

YX8019 has one or two 1.25V rechargeable batteries to illuminate the LED stably. When the sun shines on the solar battery, it charges the rechargeable battery, and at night, the charged rechargeable battery turns on the LED and automatically switches.

A solar LED driver is a device that controls and powers LED lights using solar energy. It is designed to work with solar panels to capture sunlight, convert it into electrical energy, and provide the necessary voltage and current to drive the LEDs.

The main function of a solar LED driver is to regulate the power supply to the LEDs, ensuring that they receive the correct voltage and current for optimal performance and longevity. It typically incorporates a power converter or regulator that adjusts the solar panel’s output to match the requirements of the LEDs. This helps prevent overvoltage or overcurrent situations that could potentially damage the LEDs.
