New Single-Chip Digitally Enhanced Power Analog Solution is Ideal for DC-DC Power Conversion
March 28 2017 - 8:03AM
A new Digitally Enhanced Power Analog (DEPA) product for DC-DC
power conversion is now available from Microchip Technology Inc.
(NASDAQ:MCHP), a leading provider of microcontroller, mixed-signal,
analog and Flash-IP solutions. The single-chip solution controls
DC-DC converters and is capable of accepting a high voltage input
(up to 42V) while simultaneously regulating a wide output voltage
range (300 mV to several hundred volts, depending on topology). The
device is ideal for industrial and automotive environments and is
particularly suited for battery charging and LED drive
applications. For more information, visit:

The MCP19215 is a dual controller, offering the ability to
control two flyback, SEPIC, boost and/or Ćuk circuits
simultaneously. The two circuits can even be different topologies.
Alternatively, it can be configured to control one power train
bidirectionally, maintaining voltage or current regulation in
either direction through the power converter. This allows the
circuit to dynamically switch between constant voltage and constant
current operation, while also switching the direction of the power
conversion. The benefits of this include the ability to use the
same power supply to control both power in to and power out of a
storage device (like a battery or a super-capacitor) while fuel
gauging. In addition, it can switch automatically between sourcing
and sinking power with a fast response time. This will maintain
power on critical system voltage rails in a server or automation
application, or conserve power in a renewable energy or automotive
application.
All of the major performance parameters are completely
configurable within the microcontroller core that is managing the
analog control loops within the device. Current limit, operating
frequency, fault responses, and over- and under-voltage lockouts
can all be tailored to the application.
The MCP19215 also features low quiescent current sleep modes and
the ability to survive load dump transient conditions, making it
ideal for automotive applications. The device can be programmed to
shut down other loads and enter sleep mode, allowing direct
connection to the battery with minimal power consumption when the
engine is not running.
Using the configurable internal registers allows for a
programmable operating frequency, with a programmable phase shift,
to coordinate the two power conversions. This reduces
electromagnetic radiation in the application, preventing
interference problems.
“Microchip continues to develop unique solutions to help solve
today’s complex power control challenges,” said Keith Pazul,
director of marketing for Microchip’s Analog, Power and Interface
Division. “Microchip offers a wide diversity of power management
methods, giving customers tailored solutions with many different
digital and analog power control technologies. Our portfolio of
DEPA controllers can provide our customers better options for
analog power conversion applications that require digital
communication or dynamic reconfiguration—needs which are not well
supported in the current market.”
Development SupportThe device is supported by
Microchip’s suite of programming and development tools including
MPLAB® X Integrated Development Environment (IDE) and the MPLAB XC8
complier. The MCP19214 and MCP19215 are featured in the ADM00799
evaluation board, controlled with an accompanying graphical user
interface, to provide flexible boost and SEPIC power conversion
examples which can easily be adapted for application needs.
Pricing and AvailabilityMCP19214 and MCP19215
are available today in a 5 x 5 QFN package starting at $3.17 in
10,000 unit quantities. For additional information, contact
any Microchip sales representative or authorized worldwide
distributor, or visit Microchip’s website. To purchase
