General Description

The MCP1631/MCP1631V is a high-speed microcon-

troller based 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 microcontrol-

ler, 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 microcontrol-

ler and auxiliary circuits.
