SE8651 is a PWM operating mode, high efficiency, simple peripheral, built-in power transistor, suitable for high-precision buck LED constant current drive chips with 5-80V input.
SE8651 can achieve two function switching, switching between two function modes through MODE: fully lit and semi lit.
The frequency of SE8651 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 SE8651 has an output short circuit protection function, and under 5V~80V input conditions, short-term short circuits will not damage the power supply components.
The SE8651 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.
