INTRODUCTION
The proliferation of distributed power supplies is expected to accelerate their use in
future generation cars. Distributed power supplies or "point-of-load" power supplies are
being used increasingly throughout. These Power Supply Units (PSUs) are responsible
for stepping up (or down) a 12V nominal bus, to power a multitude of subsystems.
These include telematics/navigation systems, power seats and doors, interior and
exterior lighting, electronic braking and engine management control.
Many automotive and industrial applications require higher voltages than are available
on the input power supply rail. Supply voltages required for these systems can range
from 36V (power seats and windows) to 1.8V (to drive low-voltage microprocessors).
In addition, depending on where the PSU operates on the automotive power bus, it may
be required to perform under very stringent power requirements.
Automotive subsystems with their inherent high voltage transients and high efficiency
requirements place increasing demands on power supply designs. These supplies
must provide high power, high efficiency and low noise from a very compact footprint
and must maintain a high efficiency over a wide range of operational input voltages.
The MCP1630/V high-speed, microcontroller-adaptable Pulse Width Modulator (PWM)
is capable of maintaining output regulation with no adverse effects on system
performance or reliability. The MCP1630 Automotive Input Boost Converter Demo
Board provides a better choice for automotive application design and high efficiency.
