General Description
T he MCP16 31/MC P1631 V is a hi gh-spe ed
analog pulse width modulator (PWM) used to develop
intelligent power systems. When combined with a
microcontroller, the MCP1631/MCP1631V will control
the power system duty cycle providing output voltage
or current regulation. The microcontroller can be used
to adjust output voltage or current, switching frequency
and maximum duty cycle while providing additional
features making the power system more intelligent,
robust and adaptable.
Typical applications for the MCP1631/MCP1631V
include programmable switch mode battery chargers
capable of charging multiple chemistries, like Li-Ion,
NiMH, NiCd and Pb-Acid configured as single or
multiple cells. By combining with a small
microcontroller, intelligent LED lighting designs and
programmable SEPIC topology voltage and current
sources can also be developed.
The MCP1631/MCP1631V inputs were developed to
be attached to the I/O pins of a microcontroller for
design flexibility. Additional features integrated into the
MCP1631HV/MCP1631VHV provide signal condition-
ing and protection features for battery charger or
constant current source applications.
For applications that operate from a high voltage input,
the MCP1631HV and MCP1631VHV device options
can be used to operate directly from a +3.5V to +16V
input. For these applications, an additional low drop out
+5V or +3.3V regulated output is available and can
provide current up to 250 mA to power a microcontroller
and auxiliary circuits.
Applications
• High Input Voltage Programmable Switching
Battery Chargers
• Supports Multiple Chemistries Li-Ion, NiMH, NiCd
Intelligent and Pb-Acid
• LED Lighting Applications
• Constant Current SEPIC Power Train Design
• USB Input Programmable Switching Battery
Chargers
