DESIGN FEATURESвЂ‰L Monolithic 2A Buck Regulator
Plus Linear Regulator Simplifies
Wide Input Voltage Applications
by Rich Philpott Introduction
Wide ranging voltage sourcesвЂ”such
as automotive batteries, unregulated
wall transformers, and industrial
power suppliesвЂ”require regulation
to provide stable output voltages
during harsh input transient conditions. Simple, robust and relatively
inexpensive linear regulators offer one
solution. They produce low output
ripple and offer excellent power supply ripple rejection, but low efficiency,
high power dissipation and thermal
constraints are problems at high input-to-output ratios.
The typical alternative to the linear
solution is a high voltage monolithic
step-down switching regulator. Switching regulators offer high efficiency,
excellent line and load regulation, and
good dynamic response, but systems
with multiple outputs require multiple
switchers. This can quickly drive up
the power supply cost, space requirements, design effort and noise. …
