Operates as an off-line quasi-resonant flyback switching regulator.
A classic, high-performance application. Drain / Startup Terminal
If the internal MOSFET shorts, this low-value resistor (typically
The standby VCC startup voltage is 16V, while the shutdown voltage (under voltage lockout) is 11V. If your PSU is "clicking" or failing to start, check that VCC charges above 16V.
Feedback Terminal. Accepts constant voltage error-signals from the optocoupler circuit to regulate the duty cycle.
integrates a power MOSFET and a controller into a single module, providing high efficiency and simplified circuit design. Sanken Electric Package Type: 5-Pin SIP (or TO-3P)
