Microchip delivers everything
a power conversion design
engineer needs: low-risk product
development, lower total system
cost, faster time to market,
outstanding technical support and
dependable delivery and quality.
An Intelligent Power Supply
does not need to be complex or
expensive. With MCUs and DSCs
from 6 to 100 pins, Microchip has
an appropriate device solution for
every application. Many simple
tasks can be implemented with a
low-cost MCU that contains basic
peripherals. For more demanding
applications, many of our MCUs
and DSCs have innovative on-chip
peripherals designed specifically for
power conversion. These peripherals
include fast PWM modules with
special operating modes and high-
speed Analog-to-Digital Converters
(ADCs) for fast acquisition of power
supply information.
