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

m u l t i p l e c e l l s . B y c o m b i n i n g w i t h a s m a l l

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.
