AOZ7501 Datasheet | Alpha & Omega Semiconductors

Features General Description AOZ7501 is a series of current mode controllers for flyback topology applications. The AOZ7501 series integrates 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, AOZ7501 includes cycle-by-cycle current limit, Under Voltage Lockout (UVLO), VDD OVP, DMAG pin OVP, Over Load Protection (OLP), CS pin protection and Secondary-Side Diode Short protection (SSDS). Applications - SMPS - NB adapter - Charger Features - Integrated HV start-up circuitry - Under-voltage lockout: 7V/15V - 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 - VDD over-voltage protection - DMAG pin over-voltage protection - Secondary-side diode short protection - CS pin protection - Internal over-temperature protection Typical Application HV GATE FB GND ^ VDD DMAG Rev. 1.0 August 2017 .aosmd.
