through the TL431 voltage reference for proper regulation.

Capacitor C11 bypasses the TL431 response for improved

ripple performance. Resistor R5 determines the AC gain of the

circuit.

The maximum power capability of TinySwitch in a given

application depends on the thermal environment (sealed

enclosure, ventilated, open frame, etc.,), transformer core size

and design (continuous or discontinuous), efficiency required,

minimum specified input voltage, input storage capacitance,

output voltage, output diode forward drop, etc., and can be

different from the values shown in Table 1.

Key Application Considerations

Audible Noise

At loads other than maximum load, the cycle skipping mode

operation used in TinySwitch can generate audio frequency

components in the transformer. This can cause the transformer

to produce audio noise. Transformer audible noise can be

reduced by using appropriate transformer construction

techniques and decreasing the peak flux density. For more

information on audio suppression techniques, please check the

levels obtainable under following conditions:

1. TheminimumDCinputvoltageis90Vorhigherfor85VAC

input or 240 V or higher for 230VAC input or 115 VAC

input with a voltage doubler. This corresponds to a filter

capacitor of 3 µF/W for universal input and 1 µF/W for 230

or 115 VAC w/doubler input.

Ceramic capacitors that use dielectrics such as Z5U, when used

inclampandsnubbercircuits, canalsogenerateaudionoisedue

to electrostriction and piezo-electric effects. If this is the case,

replacing them with a capacitor having a different type of

dielectricisthesimplestsolution. Polyesterfilmcapacitorsand

ceramic capacitors with dielectrics such as NPO or X7R are

good alternatives.

2. A secondary output of 5 V with a Schottky rectifier diode.

3. The P and G packaged parts are board mounted with source

pinssolderedtosufficientareaofcopperandtheYpackaged

parts are heat sinked sufficiently to keep the die temperature

at or below 100 °C.
