AP65550FN-7 Description

Short technical summary and product information.

The AP65550FN-7 from Diodes Incorporated is a 5A adaptive constant-on-time (COT) mode synchronous buck converter. Designed for high-efficiency, low-voltage regulation, it offers excellent transient response and high DC output accuracy.

 

This device features a wide input voltage range of 4.5V to 18V and an output voltage range from 0.765V to 6V. The switching frequency is fixed at 650kHz. It incorporates internal high-side (65mΩ) and low-side (36mΩ) switches for synchronous rectification. The converter supports both low ESR and ultra-low ESR output capacitors.

 

Key features include built-in over-current limit and thermal shutdown protection, programmable soft-start, and pre-biased start-up. The AP65550FN-7 is available in a 10-UFDFN exposed pad package, suitable for surface mounting.

 

Applications for this converter include gaming consoles, flat-screen TV sets and monitors, set-top boxes, distributed power systems, and consumer electronics.
