By operating at higher fixed switching frequencies of 500kHz and 750kHz, these highly integrated converters are also able to help shrink circuit footprints by minimizing the size of external inductive and capacitive components. The 500kHz 4A-rated AP65402 and 5A-rated AP65502 provide an adjustable output voltage range of 0.925V to 16V, while the 750kHz equivalents, the AP65403 and AP65503, offer a higher range of 2.5V to 16V.

A wide operating voltage range of 4.75V to 17V means the converters are suited for both 5V and 12V bus system design and all devices tolerate a transient peak voltage of up to 7A. Component packaging is the industry-standard exposed pad SO-8EP, with pin-outs identical throughout the product family.
