APPLICATION CIRCUITS/
ISSUES
5.1
Typical Applications
The MCP1630 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.
5.2
NiMH Battery Charger Application
A typical NiMH battery charger application is shown in
the
“Typical Application Circuit”
on page 3 of this
data sheet. In that example, a Single-ended Primary
Inductive Converter (SEPIC) is used to provide a con-
stant 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.
5.3
Multiple Output Converters
By using additional MCP1630 devices, multiple output
converters can be developed using a single microcon-
troller. If a two-output converter is desired, the micro-
controller can provide two PWM outputs that are
phased 180° apart. This will reduce the input ripple
current to the source and eliminate beat frequencies.
