SE8652 is a PWM operating mode, high efficiency, simple peripheral, built-in power transistor, suitable for high-precision buck LED constant current drive chips with 5-100V input.
SE8652 can achieve two functional switching modes: fully lit and semi lit through MODE.
The frequency of SE8652 is fixed at around 165 Khz, and a built-in jitter circuit can reduce EMI interference to other devices. In addition, using the average current sampling mode can improve the current accuracy under wide input voltage conditions.
The SE8652 has an output short circuit protection function, and under 5V~100V input conditions, short-term short circuits will not damage the power supply components.
The SE8652 also has the function of over temperature regulating current. When the temperature inside the chip reaches around 140 ° C, the output current will be automatically lowered.
