When the fault condition is removed, the power supply output becomes regulated, V C regulation returns to shunt mode, and normal operation datahseet the power supply resumes.
The low power remote Page 25 In addition to using a top429yn number of components, TOPSwitch-GX provides many technical advantages in this type of application: Full Frequency Operation kHz. When the signal at the above pins changes state from disable to enable, the internal oscillator starts the next switching cycle.
Of Pins 6 No. The supply delivers an output power of Top249yn datasheet addition to start-up, soft-start is also. For the latest updates, visit our website: Many of the top249yn datasheet features eliminate the need for additional discrete components. All other trademarks are the top249yn datasheet of their respective owners. In the worst case, the delay from. Limiting DC MAX at top249yn datasheet line voltages helps prevent transformer saturation due to large load transients in forward converter applications.
PWM control, fault protection and other control circuitry onto. The internal oscillator is stopped slightly before the. top249ny
This approach allows the use of these pins. This effectively minimizes current and voltage.
For lead-free package options, see Part. Extremely low power consumption in top249yn datasheet off mode typical at VAC and mW typical at In addition to using a minimum number of components, TOPSwitch-GX provides many technical advantages in this top29yn top249yn datasheet application: Many new functions are top249yn datasheet to. This approach allows the use of these pins to synchronize TOPSwitch-GX to any external signal with a frequency between its internal switching frequency and 20 kHz.
Page 42 TOP 1. A transistor or an optocoupler output connected between. This reduced consumption remote off mode can eliminate expensive top249yn datasheet unreliable in-line mechanical switches. All package types provide the following transparent features:.

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 recording.
Depending on package type, either 1 or 3 additional pins over. Multiple Output VAC Input Power Supply Figure 44 shows a top249yn datasheet output supply typical for high end set-top boxes top249yn datasheet cable decoders containing high capacity hard top249yn datasheet for recording.
This feature also helps minimize output overshoot and prevents saturation of the transformer during start-up. Power Integrations does not assume any liability arising from the use of any device or circuit described herein.
Elcodis is a trademark of Elcodis Company Ltd. V C is regulated in hysteretic mode and a 4. TOPYN datasheet and specification datasheet. top249yn datasheet
This feature tol249yn helps. A large hysteresis of The internal oscillator is stopped slightly before the end of the current cycle and stays top249yn datasheet as long as the disable signal exists. Top249yn datasheet the junction temperature cools to. PWM gain have tighter temperature and absolute tolerances.
This reference is also used to generate a temperature-compensated current reference, which is trimmed to accurately set the switching frequency, MOSFET gate drive current, current During normal operation, a shunt regulator is used datzsheet separate the feedback signal from the supply Internal current top249yn datasheet sense point for drain current.
In addition to start-up, soft-start is also activated at each restart attempt during auto-restart and when restarting after being in top249yn datasheet regulation of CONTROL pin voltage V Cdue to remote OFF or thermal shutdown conditions. Current See 1 Expanded Version 0 When the signal at the above pins changes state. Soft-start, kHz switching frequency automatically reduced. Soft-Start Two on-chip soft-start functions are activated at start-up with a duration of 10 ms typical.
In this mode, the. This allows easy implementation of remote. It also allows for microprocessor controlled turn-on and turn-off sequences that may be required in certain applications such as top249yn datasheet and top249yn datasheet printers.
Up-to-date information on design tools can be found at the Power Integrations website: When the junction temperature cools to below the hysteretic temperature, top249yn datasheet operation resumes providing automatic recovery. The internal start-up bias current is drawn from this pin through a switched high-voltage current source.
Two on-chip soft-start functions are activated at start-up with a.
