X-capacitor discharge IC for stringent standby, no-load requirements

What happened

Power Integrations is expanding its CAPZero family of X-capacitor discharge ICs with the fourth-generation CAPZero-4 device, for industrial and consumer applications. The device reduces system no-load and standby input power by up to 1000 mW, consumes less than 1 mW to support zero-watt no-load operation, operates from -40°C to 125°C, meets IEC 60335 X-capacitor discharge of <34 V in <1 sec, covers X capacitor values from 100 nF to 6 mF, features 900 V internal MOSFETs, and is NEMKO and CB certified. It is pin-to-pin and package compatible with previous CAPZero devices, allowing adoption without redesign. According to the company, the device is in production and shipping to customers.
