ABB RET670 protection device is a protection device with non-destructive zero crossing detection function, launched by Power Integrations. It adopts a compact SO-8C package, suitable for non isolated buck and buck boost power supplies with output currents up to 575 mA, and provides up to 12 W output for general-purpose input isolated flyback designs. The RET670 protection device integrates offline power conversion, non-destructive zero crossing detection, and optional X-capacitor discharge function in a small package.
This protective device can achieve 3% adjustment on the line and load, with no-load power consumption less than 30 mW and IC standby current less than 100 A under external bias. Compared to discrete designs, the Link Switch TNZ IC can reduce the number of components by 40% or more. In addition, this IC can provide high light load efficiency, thereby supporting more system characteristics while meeting strict standby regulations, such as compliance with CE certification.
