POWER INTEGRATIONS RDK-91 Reference Design Kit, Flyback 12W Power Supply, Using TinySwitch®-III IC
The is a universal input, 12V, 1A flyback power supply using a TNY278PG device from the Tinyswitch-III family of ICs. The board provides a number of user configurable options which are designed to demonstrate the features and flexibility of the TinySwitch-III family. These include easy adjustment of the device current limit for increased output power or higher efficiency operation, and a latched output overvoltage shutdown.
- .
- Meets all existing and proposed harmonized energy efficiency standards including
- .
- No load consumption 140mW at 265VAC no bias winding required
- .
- Greater then 75% active mode efficiency exceeds standards requirement of 71%
- .
- BP/M capacitor value selects power MOSFET current limit for greater design flexibility
- .
- Output overvoltage protection using primary bias winding sensed shutdown
- .
- Increases MOSFET and magnetics power delivery
- .
- Reduces overload power, which lowers output diode and capacitor costs
- .
- Integrated TinySwitch-III safety/reliability
- .
- Meets EN550022 and CISPR-22 class B conducted EMI with greater then 12dBµV margin
- .
- Meets IEC61000-4-5 class 3 AC line surge
