Product Overview

The JP7035S and JP7045S are high-performance quasi-resonant AC/DC power management ICs designed for offline flyback converters. Both devices support a wide 7V to 60V VDD supply range, making them suitable for PD and QC fast-charging power applications. The controllers automatically operate in DCM / QR modes according to input voltage, output voltage, and load conditions, and enter Burst Mode under light-load operation to optimize efficiency over the full operating range while achieving standby power consumption below 75mW.

JP7045S further integrates a 650V GaN MOS, enabling higher integration and simplified system design for compact, high-efficiency charger and adapter applications.
