CAP200DG-TL – Power Integrations CAPZero-2 Zero Loss X-Capacitor Discharge IC

Quick Answer The CAP200DG-TL is a member of Power Integrations' CAPZero-2 family, an automatic X-capacitor discharge IC designed to eliminate power loss in X-capacitor discharge resistors. When AC voltage is present, it blocks current through the discharge resistors (reducing no-load consumption to less than 5 mW). When AC is removed, it safely discharges the X-capacitor to below 30V within 1 second. Housed in a compact SO-8 package, it supports X-capacitors from 100 nF to 6 μF and is ideal for all universal input offline power supplies.
