FAN6300AMY Description

Short technical summary and product information.

The FAN6300AMY from On Semiconductor is a highly integrated PWM controller designed to enhance the performance of flyback converters. It supports quasi-resonant operation, reducing switching losses and improving efficiency across a wide range of line voltages and load conditions.

 

Key features include a built-in High-Voltage startup circuit for faster controller startup and a proprietary green-mode function for minimizing standby and light-load power consumption. The controller offers robust protection mechanisms such as pulse-by-pulse current limiting, auto-recovery open-loop protection, and over-voltage protection. The gate output is clamped at 18V to protect the power MOSFET.

 

This controller is suitable for applications requiring low operating frequency (below 100 kHz) for the FAN6300A variant. It is available in an 8-pin SOIC package, suitable for surface mounting.

 

Applications include AC/DC NB adapters and open-frame switch-mode power supplies (SMPS).
