Maxim's MAX17509 integrates two 3 A internal switch step-down regulators with programmable features. The device can be configured as two single-phase, independent, 3 A power supplies or as a dual-phase, single-output, 6 A power supply. The device operates from 4.5 V to 16 V input and generates independently adjustable output voltage in the ranges of 0.904 V to 3.782 V, and 4.756 V to 5.048 V, with ±2% system accuracy.

This device provides maximum flexibility to end-users by allowing them to choose multiple programmable options by connecting resistors to the configuration pins. Two key highlights of the device are the self-configured compensation for any output voltage and the ability to program the slew rate of LX switching nodes to mitigate noise concerns. In noise-sensitive applications, such as high-speed multi-gigabit transceivers in FPGAs, RF, and audio benefit from this unique slew rate control. SYNC input is provided for synchronized operation of multiple devices with system clocks.

MAX17509 offers output over-voltage (OV) and under voltage (UV) protection, as well as overcurrent (OC) and undercurrent (UC) protection with a selectable hiccup/latch option. It operates over the -40°C to 125°C temperature range, with thermal sensing and shutdown provided for over temperature (OT) protection. The device is available in a 32-pin 5 mm x 5 mm TQFN package.
