Product details

product description

FM8301 (SOT23-4) is a high-precision non-isolated step-down LED constant current control chip. The chip works in the critical mode of inductor current and is suitable for non-isolated step-down LED lighting applications in the full voltage range of AC85V~AC264V.

The FM8301 (SOT23-4) chip integrates a 500V power switch, adopts high-precision sampling, compensation circuits and high-voltage JFET power supply technology, without VCC capacitors and startup resistors, and without any external compensation circuits and feedback circuits. The internal application of the chip is accurate and stable. The adaptive technology of the system makes the system periphery very simple, and can achieve high-precision LED constant current output and excellent line voltage adjustment rate under the condition of very few peripheral components, which greatly saves the system cost and volume. The FM8301 (SOT23-4) chip works in critical inductor current mode, and the output current does not change with changes in inductance and LED operating voltage, thereby achieving excellent load regulation.

FM8301 (SOT23-4) has multiple protection functions, including LED short-circuit protection, chip power supply under-voltage protection, chip over-temperature adjustment, etc.

FM8301 (SOT23-4) adopts SOT23-4 package, the package volume is small, and the PCB wiring area is saved to the greatest extent.
