The MCP1630/V high-speed PWM can be used for any
circuit topology and power-train application when
combined with a microcontroller. Intelligent, cost-
effective power systems can be developed for applica-
tions that require multiple outputs, multiple phases,
adjustable outputs, temperature monitoring and
calibration.
power converter example is shown using the
MCP1630V. In this application, when the ac-dc input
power is present, the bidirectional power converter is
used to charge 4-series Li-Ion batteries by boosting the
input voltage. When ac-dc power is removed, the
bidirectional power converter bucks the battery voltage
down to provide a dc bus for system power. By using
this method, a single power train is capable of charging

NiMH Battery Charger Application
4-series cell Li-Ion batteries and efficiently converting
the battery voltage down to a low, usable voltage.

data sheet. In that example, a Single-Ended Primary
Inductive Converter (SEPIC) is used to provide a
constant charge current to the series-connected
batteries. The MCP1630 is used to regulate the charge
current by monitoring the current through the battery
sense resistor and providing the proper pulse width.
The PIC16F818 monitors the battery voltage to provide
a termination to the charge current. Additional features
(trickle charge, fast charge, overvoltage protection,
etc.) can be added to the system using the programma-
bility of the microcontroller and the flexibility of the
MCP1630.
DS21896B-page 16
By using additional MCP1630 devices, multiple output
converters can be developed using a single MCU. If a
two-output converter is desired, the MCU can provide
two PWM outputs that are phased 180° apart. This will
reduce the input ripple current to the source and
eliminate beat frequencies.
