MCP16251 and MCP1640B Synchronous Boost
Converters Evaluation Board (ADM00458)
The MCP16251 and MCP1640B Synchronous
Boost Converters Evaluation Board is used
to evaluate and demonstrate the MCP16251
and MCP1640B in two boost-converter
applications with multiple output voltages.
It can be used to evaluate both package
options (SOT-23-6 and 2 × 3 mm 8-pin (T)DFN). Three
common output voltages can be selected: 2.0V, 3.3V and
5.0V. The output voltage can be changed with a mini-dip
switch that changes the external resistor divider. A switch
connected to the EN pin is used to enable and disable the
converters. When enabled, the MCP16251/MCP1640B
will regulate the output voltage; when disabled, the
MCP16251/MCP1640B disconnects the path from input
to output for “true-disconnect”.
MCP16331 Buck Converter Evaluation Board
(ADM00519)
The MCP16331 Buck Converter Evaluation
Board is used to evaluate and demonstrate
the MCP16331 in the SOT-23 package.
This board demonstrates the MCP16331
in a buck converter application with two
selectable output voltages. Test points are provided for
the input and output, allowing the board to be connected
directly to a system. Additional test points provide access
to the EN pin to modify the state of the converter and
access to the software pin to view the switching waveform.
MCP19114 Flyback Stand-alone Evaluation Board
(ADM00578)
The MCP19114 Flyback Stand-alone
Evaluation Board and GUI demonstrate the
MCP19114's performance in a synchronous
Flyback topology. It is configured to
regulate load current and is well suited
to drive LED loads. Nearly all operational
and control system parameters are programmable
through the integrated PIC MCU core. The MCP19114
evaluation board comes preprogrammed with firmware
designed to operate with the GUI interface. MPLAB X
IDE can be used to develop and program user-defined
firmware, customizing it for the specific application. The
evaluation board contains headers for ICSP as well as I
2
C
communication. Several test points have been designed
into the PWB for easy access and development purposes.
The MCP19114-Flyback Stand-alone Evaluation Board also
demonstrates an optimized PCB layout that minimizes
parasitic inductance, while increasing efficiency and power
density. Proper PCB layout is critical to achieving optimum
MCP19114 operation as well as power train efficiency and
noise minimization.
Thermal Management
MCP9700 Thermistor Demo Board (MCP9700DM-TH1)
This demo board contains analog circuitry to measure
temperature. The board uses BC Components’
232264055103 NTC thermistor to convert temperature
to resistance. The thermistor is placed in a voltage divider
which converts resistance to voltage. This voltage is
filtered and placed at the MCP6S22 Programmable Gain
Amplifier’s (PGA) CH0 input. The PGA gains and buffers
the thermistor.
MCP9800 Temperature Sensor Demonstration
Board (MCP9800DM-TS1)
The MCP9800 Temperature Sensor
Demonstration Board can be connected to
a PC using the USB interface to allow you
to evaluate the sensor's performance. The
7-Segment LED displays temperature in degrees Celsius
or degrees Fahrenheit. The temperature alert feature
can be set using the on-board potentiometer. An alert
LED is used to indicate an over-temperature condition.
Temperature can also be datalogged using the Thermal
Management Software GUI. The sensor registers can also
be programmed using the GUI.
USB Peripherals
MCP22XX Family of USB Bridge Breakout Modules
(MCP2200 = ADM00393; MCP2210 = ADM00419;
MCP2221 = ADM00559)
These breakout modules and supporting
software demonstrate USB Bridge
capabilities and allow the development of
custom software.
UCS1002 USB Charging Controller – SMBus
(ADM00497)
The UCS1001 USB port power controller provides a single
USB port power switch capable of up to 2.5 amps of
continuous current as well as a USB 2.0 compliant data
switch. When a portable device is plugged in, it can auto-
cycle through up to seven preloaded charger emulation
profiles until charging commences. The embedded profiles
are compatible with BC1.2 CDP, DCP, YD/T-1591 as well
as most Apple® and RIM® portable devices. It also allows
portable device charging when an application or host is in
standby or in a sleep state.
UCS81003 Evaluation Board (ADM00561)
The UCS81003 Evaluation Board allows
you to evaluate the features of the
UCS81003 Automotive USB Port Power
Controller with Charger Emulation. The
board allows the UCS81003 to be tested in different
configurations by populating jumpers on specific
header locations.
