Step 1: Gather the Materials! So with any prototyping project this really shouldn’t be the first step… But we’re gonna go ahead and do it cuz it’s just so darn fun! Just a little disclosure, we’ll be using the ACT4088 picked because it’s cheap and has an adjustable VOut along with a max of 1.5A …

The LM5017 is a 600 mA constant on-time synchronous buck regulator with built-in high side and low side MOSFETs. This device has a wide input voltage range from 7. 5 V to 100 V. The constant on-time control scheme used in this device doesn’t need loop compensation, delivers excellent transient response, and enables very high …
