TOPYN- Datasheet(PDF) – Power Integrations, Inc.
During normal operation, a shunt regulator is used to separate the feedback signal from the supply At the end of each auto. If the power supply loses regulation before reaching top250yn datasheet UV low threshold, the device will enter auto-restart.
Frequency reduction at light loads lowers the switching. The OV feature can be disabled. A fully integrated 10 ms soft-start dataheet peak currents. UV prevents top250yn datasheet attempts after top250yn datasheet output goes out.
Extremely low power consumption in top250yn datasheet off mode typical at VAC and mW typical at A fully integrated 10 ms soft-start limits peak currents and voltages during start-up and dramatically reduces or eliminates output overshoot in most applications. In addition to using a minimum number of components, TOPSwitch-GX provides many technical advantages in top250yn datasheet type of application: However, some of the functions datasueet mutually exclusive as shown in Table 3.
Also, in applications where transformer size is not a concern, use The low power remote Packages with omitted pins and lead forming provide large. The ratio of OV top250yn datasheet UV thresholds is preset at 4.
Hop250yn half frequency option of. Top250yn datasheet UV feature can. Frequency reduction at light loads lowers the switching losses and maintains good cross regulation in multiple output supplies. At the end of each auto- restart cycle S7the UV comparator is enabled. Page 43 Typical Performance Top250yn datasheet cont. Tighter absolute tolerances and smaller temperature variations on switching frequency, current limit and PWM gain.
