Zest_Power_12-48V-to-10V

Overview

The Zest_Power_12-48V-to-10V is an electronics development board for 6TRON opensource platform based on MAX17506 from Maxim.

The MAX17506 is a high-voltage, synchronous step-down DC-DC converter with integrated high-side MOSFET operates over a 4.5V to 60V input.The converter can deliver up to 5A and generates output voltages from 0.9V up to 0.9 x VIN and features an adjustable switching frequency for optimum efficiency. The feedback (FB) voltage is accurate to within ±1.4%.

The Zest_Power_12-48V-to-10V offers 6TRON users a Step-Down DC-DC Converter for powering the 6TRON stacks from an external high voltage supply voltage 12 to 48V range.
