Product details

Wide-input buck regulator in a 3x3 TDFN

The MAX17761ATC+ is a step-down (buck) switching regulator from Analog Devices, delivering up to 1A of continuous output current from a 4.5V to 76V input rail. The output is adjustable from 0.8V up to 68.4V, making it suitable for generating a wide range of regulated voltages from high-voltage supplies like 48V telecom or 72V industrial buses.

Switching frequency and efficiency

The switching frequency is programmable via an external resistor from 200 kHz to 600 kHz, allowing the designer to trade off inductor size against switching losses. An integrated synchronous rectifier eliminates the need for an external freewheeling diode, improving efficiency at the 1A load point.

Package and thermal performance

Housed in a 12-lead WFDFN with an exposed pad (3 mm x 3 mm TDFN package), the MAX17761ATC+ relies on the pad soldered to the PCB ground plane for heat dissipation.
