Product Overview

The RDK-91 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
