| AOZ7523 Current Mode Flyback Converter with HV Start-Up and Advanced Features AOZ7523 is a series of current mode controllers with a 650V integrated power MOSFET, and a X-capacitor discharge function Bleeding Resistor Removal, BRR , Brown-In/Brown-Out Lossless Brown-Out, 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, AOZ7523 includes cycle-by-cycle current limit, Under Voltage Lockout UVLO , VDD OVP, DMAG pin OVP, Over Load Protection OLP , CS pin protection, Secondary-Side Diode Short protection SSDS . SMPS NB Adapter Charger Integrated with 650V HV MOSFET Integrated bleeding resistor removal function Integrated brown-in/brown-out function Integrated HV start-up circuitry Under-voltage lockout 7V/15V Low operation current Lower operation current in skip mode <450uA Built-in 65kHz/130kHz operation frequency Current mode control Soft-start Leading edge blanking function on current sense Built-in slope compensation Cycle-by-cycle current limit Minimum on time modulation to minimize acoustic noise Frequency foldback mode and skip mode operation Frequency spread by spread spectrum clock generator SSCG VDD over-voltage protection Dmag pin over-voltage protection Secondary-side diode short protection CS pin protection Internal over-temperature protection AOZ7523 HV Drain Source CS FB Dmag Page 1 of 15 AOZ7523 Ordering Information Ambient Temperature Range Package Environmental AOZ7523XAI -40°C to +125°C SO-13 Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
