SW8603 datasheet


The SW8603 is built for switching power supply High Voltage MOSFET current-mode PWM controller family. The circuit is low standby power consumption, low starting current. In standby mode, the power Road enters hiccup mode, thus effectively reducing the standby power circuit. The switch frequency is 67KHz, the jitter of the oscillation frequency can be obtained to be low EMI. Built-in 15ms soft start circuit can be reduced during power transformer Stress, prevent transformer saturation.




1. Low starting current (6μA)

2. Jitter oscillation frequency can reduce EMI

3. Overcurrent protection

4. Overvoltage protection

5. Undervoltage lockout

6. Built-in temperature protection

7. Internal integrated high voltage MOSFET


1. Battery charger power supply

2. Portable device power supply

3. DVD, DVB power supply

4. Adapter
