Overview
MAX17509 EVALUATION KIT AVAILABLE 4.
5V–16V, Dual 3A, High-Efficiency, Synchronous Step-Down DC-DC Converter with Resistor Programmability General Description The MAX17509 integrates two 3A internal switch step-down regulators with programmable features.
The device can be configured as two single-phase independent, 3A power supplies or as a dual-phase, single-output 6A power supply.
The device operates from 4.
5V to 16V input and generates independently adjustable output voltage in the ranges of 0.
904V to 3.
782V and 4.
756V to 5.
048V, with ±2% system accuracy.
This device provides maximum flexibility to the end-user by allowing 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 highspeed 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 overvoltage (OV) and undervoltage (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 overtemperature (OT) protection.
The device is available in a 32-pin 5mm x 5mm TQFN package.
