Portable Power Conversion Design Guide
Evaluation Boards
Microchip offers a number of boards to help evaluate
device families. Contact your local Microchip sales office
for a demonstration.
AAAA Clock Demo
A PIC microcontroller performs basic clock functions on
a LCD display using a single AAAA battery boosted up to
3.3V using a MCP1624. The demo includes capacitive
touch controls and battery fuel measurement.
MCP1252 Charge Pump Backlight Demonstration
Board (MCP1252DM-BKLT)
The MCP1252 charge pump is set up for
biasing backlighting or driving other LED
applications, with intensity, dimming and
disabling features.
MCP1602 Evaluation Board (MCP1602EV)
The board evaluates the PFM and PWM
operation of the MCP1602 buck regulator
step down the input voltage, with
selectable output voltages.
MCP16251 and MCP1640B Synchronous Boost
Converters Evaluation Board (ADM00458)
Two boost converters are available, with selectable output
voltage levels and enable/disable capability.
MCP16301 5V/600mA Low Noise Evaluation Board
(ADM00433)
The MCP16301 boost converter runs at
high frequency to obtain a high efficiency
5V regulated output with minimal radiated
noise for use in sensitive applications.
MCP1630 Boost Mode LED Driver Demo Board
(MCP1630DM-LED2)
The MCP1630 takes an input voltage
between 9 and 16V DC, and boosts it
to provide a constant 350 or 700 mA
(selectable) current for powering up to a
30W string of LEDs.
MCP1630 NiMH Battery Charger Demonstration
Board (MCP1630DM-NMC1)
The MCP1630 is interfaced to the
PIC16LF818 to develop a fault-tolerant
NiMH battery charger with fuel gauge
capability using a 1 MHz SEPIC converter.
MCP1630V Bi-directional Four-Cell Li-Ion Charger
Reference Design (MCP1630RD-DDBK3)
The MCP1630V is set up to boost a
low source voltage to charge four Li-Ion
series cells, or current can be reversed
to provide regulated output from the Four-
cell Li-Ion battery pack to other circuits.
MCP1630 Li-Ion Multi-Bay Battery Charger
Reference Design (MCP1630RD-LIC1)
This circuit is capable of charging two single-cell Li-Ion
battery packs in parallel utilizing an input voltage of 10V to
30V, providing a constant current—constant voltage charge
with preconditioning, cell temperature monitoring and
battery pack fault monitoring.
MCP16301 High-Voltage Buck-Boost Demo Board
(ADM00399)
Using small surface-mount components
in a minimal board area, this board is
designed to operate from a 5V to 30V
input and regulate the output to 12V.
MCP1631HV Digitally-Controlled Programmable
Current Source Reference Design
(MCP1631RD-DCPC1)
The MCP1631HV is set up in a SEPIC
power converter which, combined with a
PIC16F616 microcontroller, can function as
a current source for driving LEDs in multiple
series or parallel configurations, charging
NiMH, NiCd, and Li-ion batteries.
MCP1631HV Multi-Chemistry Battery Charging
Reference Design (MCP1631RD-MCC2)
Using a PIC16F883 microcontroller in
combination with the MCP1631HV high-
speed analog PWM controller, this design
can charge one to five NiMH or NiCd
batteries; one- or two-cell Li-Ion batteries;
or drive one or two 1W LEDs.
