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.","metaTitle":"MAX17761ATC+ Analog Devices Buck Regulator, 1A, 76V Input","metaDescription":"MAX17761ATC+ step-down buck regulator from Analog Devices. 1A output, 4.5V to 76V input range, adjustable output, 12-TDFN.
