AOZ7648QI-06
AOZ7648QI-06 is Super Transient Response Converter manufactured by Alpha & Omega Semiconductors.
Description
The AOZ7648QI-06 is a secondary side control flyback converter with super transient control scheme. It supports I2C mand for fine accuracy adjustable constant voltage regulation and constant current regulation function.
A proprietary constant ON time (COT) control with input feed-forward pensation for fast transient response and good stability.
The device features include multiple protection functions such as VDD under-voltage lockout (UVLO), output under-voltage protection (UVP), output over-voltage protection (OVP) and internal over-temperature protection (OTP).
The AOZ7648QI-06 is available in a 6mm×6mm QFN38L package.
