MCP16323 Evaluation Board (ADM00427)
This small footprint, high-current-density buck circuit
provides up to 3A at 3V from an input voltage between
6.0 and 18V.
MCP1640 12V/50 mA Two Cells Input Boost
Converter Reference Design (ARD00386)
Using inputs between 2.0 and 5.0V
typical of a two-cell battery pack, this
MCP1640 boost converter can generate
high 9, 12 or 24V outputs.
MCP1640 Single Quad-A Battery Boost Converter
Reference Design (MCP1640RD-4ABC)
This design uses a single quad-A battery and boosts the
1.5V input to a 3.3V output, including an enable feature to
greatly reduce the standby current consumption.
MCP1640 Sync Boost Converter Evaluation Board
(MCP1640EV-SBC)
Using input voltages between 0.35V and
5.5V, the MCP1640 generates either a 2.0,
3.3 or 5.0V regulated output (provided the
input voltage is below the output voltage).
MCP1643 Synchronous Boost LED Constant
Current Regulator Evaluation Board (ADM00435)
Powered by one-cell or two-cell
Alkaline, NiCd or NiMH batteries,
the MCP1643 is used in a compact,
high-efficiency, fixed-frequency, step-
up DC/DC converter optimized as an LED constant current
generator, with a minimum number of external components
for applications.
MCP19035 600 kHz Synchronous Buck Controller
Evaluation Board (ADM00445)
This is a compact, highly efficient,
step-down voltage regulator that will
convert the input voltage rail (typically
12V) to a regulated 1.8V output voltage
with 10A of current.
MCP19111 Evaluation Board (ADM00397)
The MCP19111 evaluation board
demonstrates the MCP19111 operation
in a synchronous buck topology. Nearly
all operation and control parameters are
programmable using the integrated PIC
microcontroller core.
MCP3421 Fuel Gauge Demo Board
(MCP3421DM-BFG)
Measures and displays battery voltage,
discharge current, usage for non-
rechargeable batteries, and can be
programmed to additionally recharge
and calculate the remaining usage for a
rechargeable Li-Ion battery.
MCP73113 OVP Single Cell Li-Ion Battery Charger
Evaluation Board (MCP73113EV-1SOVP)
This design charges a Li-Ion battery at
500 mA or 1000 mA. It includes LED
status indicators, precondition, termination,
and auto-recharge features, at a fixed
4.20V output.

Current Control (MCP73871DM-VPCC)
When the input voltage is present,
the MCP73871 board can charge a
single-cell Li-Ion or Li-polymer battery
while powering a load, or when the
input voltage is removed, it can power
the load from the battery. The circuit
features input current limits, constant current/constant
voltage charging and LED indicators for charge status.
MCP73X23 OVP Lithium Iron Phosphate Battery
Charger Evaluation Board (MCP73X23EV-LFP)
This board contains two circuits: an MCP73123 design
to charge a single-cell LiFePO4 battery and a MCP73223
implementation to charge a dual-cell LiFePO4 battery.
MCP73837/8 AC/USB Dual-Input Battery Charger
Evaluation Board (MCP7383XEV-DIBC)
