Key Applications

• Factory Automation

Within the factory automation space, which includes

many different applications, one key need is the ability

to generate less heat. Heat within the system must be

managed, prevent overheating and shutdown. The

MAX17570 produces less heat as it is a fully synchronous

DC-DC with integrated FETs with high efficiency. The

more efficient a switching regulator is, the less it loses

the power and therefore create less heat in the system.

• Aftermarket Automotive

An example of within the aftermarket automotive space

where the MAX17570 provides a benefit is asset

tracking application. Asset tracking has increased in

popularity as the ability to wireless connect to these

monitors has become easier. Typically, these units are

designed to be as small as possible. The MAX17570 has

integrated FETs, integrated compensation, and can

even have pre-programmed output voltages, all

delivering a small solution size. Small size and fewer

components help drive overall design cost down for the

system.

• General Point of Load

General point of load is just that, a generic term. It

applies to a switching regulator that serves many

applications and design environments. Critical to any

environment is the robustness of the power conversion.

With an operating range of -40°C to +125°C, current limit

protection, overtemperature protection, and the ability to

adhere to the CISPR-32 class B emission standards, the

MAX17570 delivers a small, highly efficient power

conversion in the most adverse environments and

provides the designer the peace of mind that it is robust

and reliable.
