UNDERVOLTAGE LOCK-OUT WITH Typical applications cover offline power supplies HYSTERESIS with a secondary power capability of 50 W in wide INTEGRATED START-UP SUPPLY range condition and 100W in single range or with doubler configuration. It is compatible from both OVER-TEMPERATURE PROTECTION primary or secondary regulation loop despite LOW STAND-BY CURRENT using around 50% less components when ADJUSTABLE CURRENT LIMITATION compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the ability to operate in stand-by mode Figure 1. Block Diagram without extra components.
