Thermal Shutdown (TSD) to Halt Latch at Overheating

The onboard protection circuits described above reduce the number of components

required and thus simplify design.

Standby Function

The standby mode is selected by simply dropping the voltage at the Z/C ((1) pin) to 3.5V or less.

The MR2000 Series supports an ideal standby mode employing a method developed by Shindengen

based on the use of small intermittent output ripples. Fig.7 and Fig.8 show the input voltage Pin,

and the waveform at Po = 1.1W (11V, 0.1A), for a worldwide input Po = 100W power supply for

TV applications.
