STMicroelectronics STEVAL-SMACH15V1 USB Adapter Evaluation Board
STMicroelectronics STEVAL-SMACH15V1 USB Adapter Evaluation Board is based on the STCH03 offline PWM controller for low standby adapters. The STEVAL-SMACH15V1 provides constant output current (CC) regulation using primary sensing feedback. The device combines a high-performance low-voltage PWM controller chip and a 650VHV start-up cell in the same package. The board also features extremely low quiescent current and burst-mode management. These features help minimize residual input consumption to less than 15mW under no-load conditions.
