Datasheet Summary
Current Mode Flyback Converter with HV Start-Up and Advanced Features
General Description
AOZ7543 is a series of current-mode controllers integrated with high voltage power MOSFET, and a Xcapacitor discharge function (Bleeding Resistor Removal, BRR), Brown-In/Brown-Out (Lossless BrownOut, LBO) plus a high voltage start-up circuitry. The series also provides frequency foldback and skip mode during light load conditions to achieve excellent light load efficiency and low power standby mode. As well as a digital Spread Spectrum Clock Generator (SSCG) to improve EMI emissions. In addition, AOZ7543 includes cycle-by-cycle current limit, Under Voltage Lockout (UVLO), VDD OVP, DMAG pin...
