ST EVAL-STCH03-45W

AC/DC，主面和辅面12V90 ~ 265VAC

Overview

STMicroelectronics' STCH03TR is a PWM quasi-resonant controller specifically designed for low standby power supplies. The built-in HV startup cell with zero power consumption, the fully integrated blocks for primary side constant current output regulation, and the advanced power management make this IC a great choice for building a high efficiency and low standby consumption power supply with high overall and excellent dynamic performances.Features: Constant current output regulation (CC) with no optocoupler: reduce the number of external components (no need of CC/CV on secondary side or sense resistor) and higher efficiency due to no sense resistor power losses, 650 V embedded high voltage startup circuitry: allows controller to achieve low standby, below 10 mW, Quasi-resonant operation: high efficiency due to zero voltage switching operation, Automatic self-supply: possibility to work in constant current down to 0 V output, Feedforward compensation: output current regulation independent from mains variation, Intelligent frequency jitter: EMI reduction, Wall plug charger smartphone/tablet, Low power adapter notebook, Qualcomm quick chargers, QC 2.0 and QC 3.0, USB PD adapters, Auxiliary power supply
