The MAX1717BEEG from Maxim Integrated is an adjustable step-down controller — a DC-DC buck regulator IC that drives external MOSFETs to produce a regulated output voltage lower than its input. It is the controller core for a switching power supply, not a complete module; the designer adds the inductor, capacitors, and pass transistors around it. Typical applications include point-of-load regulation in telecom, networking, and computing equipment where a tightly regulated rail must be derived from a higher-voltage bus.
Lifecycle and compliance reality
The part is RoHS non-compliant, containing lead.
