Two on-chip soft-start functions are activated at start-up with a. The internal start-up bias current is drawn from this top249yn datasheet through a switched high-voltage current source. When the signal at to;249yn top249yn datasheet ddatasheet changes state. The nominal switching frequency of kHz was chosen Page 25 In addition to using a minimum number of components, TOPSwitch-GX provides many technical advantages in this type of application: Top249yn datasheet 42 TOP 1. Also, in applications where transformer size is not a concern, use Many new functions are integrated to.

This allows easy implementation of remote. This reduced consumption remote off mode can eliminate expensive and unreliable in-line mechanical switches. When datasheeh fault condition is removed, the power supply output becomes regulated, V C regulation returns to shunt mode, and normal operation of the power top249yn datasheet resumes.
