General Description
The device is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control.
The power MOSFET allows a very high input Vac to be applied, just limited from its breakdown voltage.
Key Features
- 800 V avalanche-rugged power MOSFET allowing ultra wide range input Vac to be achieved.
- Embedded HV start-up and sense FET.
- PWM current-mode controller.
- OCP with selectable threshold (IDlim) and 2nd OCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode.
- 30 mW no-load consumption at 230 Vac.
- Two operating frequencies:.
- 60 kHz (L type) or 115 kHz (H type).
- Jittered frequency reduces the EMI.
