AOZ7543XAI
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.
Key Features
- Integrated with HV MOSFET
- Integrated bleeding resistor removal function (CB certificate reference no. DK-64852-UL)
- Integrated brown-in/brown-out function
- Integrated HV start-up circuitry
- 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
