Контроллер питания

Маркировка:  DK112
Корпус: DIP-8

Offline switching power control chip

: AM-22A

Технические параметры:

Full voltage input 85V-265V.
Built-in 700V power tube.
A high-voltage constant-current startup circuit is integrated in the chip, and no external startup resistor is required.
Patented self-powered technology, without external winding power supply.
Standby power consumption is less than 0.3W.
65KHz PWM switching frequency.
Built-in frequency conversion function, automatically reduce the working frequency when standby, and meet the European green energy standard (<0.3W) at the same time
When the output voltage ripple is reduced.
Built-in slope compensation circuit to ensure circuit stability at low voltage and high power output.
Frequency jitter reduces the cost of EMI filtering.
Over temperature, over current, over voltage and output short circuit, secondary open circuit protection.
4KV anti-static ESD test.
