General Description

The MCP1631/MCP1631V is a high-speed
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.

Conditions

Note 1:

External Oscillator Input (OSC

IN

) rise and fall times between 10 ns and 10 µs were determined during device 

characterization testing. Signal levels between 0.8V and 2.0V with rise and fall times measured between 10% and 90% 
of maximum and minimum values. Not production tested. Additional timing specifications were fully characterized and 
specified that are not production tested.

2:

The minimum V

IN

 must meet two conditions: V

IN

 ≥ 3.5V and V

IN

 

 ≥ (V

OUT(MAX)

 + V

DROPOUT(MAX)

).

 / (V

R

 * 

ΔTemperature), V

OUT-HIGH

 = highest voltage measured over the 

temperature range. V

OUT-LOW

 = lowest voltage measured over the temperature range.

4:

Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output 
voltage due to heating effects are determined using thermal regulation specification TCV

OUT

.

5:

Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured 
value with an applied input voltage of V

OUT(MAX)

 + V

DROPOUT(MAX)

 or 3.5V, whichever is greater.
