MC44605P Description

Short technical summary and product information.

The ON Semiconductor MC44605P is an offline switch IC utilizing flyback topology for power management applications. It is designed for AC-DC converters, offering an isolated output.

 

Key electrical specifications include an input voltage range of 7.5V to 18V, a startup voltage of 14.5V, and a maximum switching frequency of up to 250kHz. The device supports a maximum duty cycle of 80% and features control functions such as frequency control, soft start, and sync. Fault protection is integrated, including current limiting, over-voltage protection, and short-circuit protection.

 

This IC does not contain internal power switches, requiring external components for switching. It is housed in a 16-pin DIP package suitable for through-hole mounting. The operating temperature range is -25°C to 150°C (TJ).

 

The MC44605P is suitable for consumer and industrial power supply applications requiring isolated output and high-frequency flyback conversion. It is often used in legacy designs and for maintaining older systems.
