PI has released a new Design Example Report (DER-572) that demonstrates a solution for small and large appliance supplies using LinkSwitch-CV, an off-line switcher featuring accurate primary-side constant-voltage (CV) control. The 10 W design has a high level of component integration, high power density, efficiency, and configurability.
- +/-5% regulation
- Tapped Buck topology delivers higher efficiency (82%) than non-isolated flyback
- Topology also reduces MOSFET stress, which is ideal for World Wide applications
- VOUT can be easily modified from 12 up to 20 V by just changing feedback resistors
