Within the Factory Automation space, which includes
many different applications, one key need is the
ability to generate less heat. Heat within the system
has to be managed, prevent overheating and
shutdown. The MAX17625/6 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 will lose power and therefore
create less heat in the system.

Point-of-Load Power Supply
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, and overtemperature
protection, the MAX17625/MAX17626 deliver a
small, high efficient power conversion in the most
adverse environments and provides the designer the
peace of mind that it is robust and reliable.

Personal Electronics
Personal Electronics are designed to be as small as
possible. The MAX17625/6 have integrated FETS,
integrated compensation, and are fully configured
using only four external components, making for a
very small solution size. Small size and fewer
components help drive overall design costs down for
the system.
