AOZ7523 Datasheet | Alpha & Omega Semiconductors

Features General Description 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). Applications - SMPS - NB Adapter - Charger Features - Integrated with 650V HV MOSFET - Integrated bleeding resistor removal function - Integrated brown-in/brown-out function - Integrated HV...
