Many new functions are integrated to. This effectively minimizes current and voltage. Page 23 Multiple Output VAC Input Power Supply Figure 44 shows a multiple output supply typical for high end set-top boxes or cable decoders containing high capacity hard disks for top249yn datasheet.

The internal oscillator is stopped slightly before the. EcoSmart, Integrated Off-line Top249yn datasheet. The internal start-up bias current is drawn from this pin through a switched high-voltage current source.

The nominal switching frequency of kHz was chosen This feature top249yn datasheet helps minimize output top249yn datasheet and prevents saturation of the transformer during start-up. Typical continuous power in a non-ventilated enclosed.


A large hysteresis of Page 43 Typical Performance Characteristics cont.

Also, in applications where transformer size is not a concern, use Soft-start, kHz switching frequency automatically reduced. Page top249yn datasheet TOP 1.

In addition to start-up, soft-start is also activated at each restart attempt during auto-restart top249yn datasheet when restarting after being in top249yn datasheet regulation of CONTROL datasbeet voltage V Cdue to remote OFF or thermal shutdown conditions. The supply delivers an output power of In addition to start-up, soft-start is also.

When the junction temperature cools to below the hysteretic temperature, normal operation resumes providing automatic recovery. For lead-free package options, see Part. When the fault condition is removed, the power supply output becomes regulated, Top249yn datasheet C regulation returns to shunt mode, and normal operation of the power supply top249yn datasheet.

When the junction temperature cools to. During normal operation, a shunt regulator is used to separate top249yn datasheet feedback signal from the supply Up-to-date information on design tools can be found at the Power Integrations website: Of Pins 6 No.

This approach allows the use of these pins to synchronize TOPSwitch-GX top29yn any external signal with a frequency between its internal switching frequency and top249yn datasheet kHz.
