Product details

Step-down regulator with wide input range

The MAX17633BATP+T is a step-down (buck) switching regulator from Analog Devices, delivering up to 3.5 A continuous output from a 4.5 V to 36 V input rail. The output is adjustable from 0.9 V up to 32.4 V, making it suitable for a range of intermediate bus or point-of-load rails in industrial and telecom systems.

Switching frequency and thermal envelope

Switching frequency is programmable from 380 kHz to 2.45 MHz, allowing the designer to trade off inductor size against switching losses. Synchronous rectification is integrated, eliminating the external Schottky diode and improving efficiency at lower output voltages.
