TYPICAL APPLICATION

A wide variety of loads can be driven in either the voltage

mode or the current mode. The most common applica-

tions use three external blocks: a low pass filter convert-

ing pulse width data to an analog output, a difference am-

plifier to monitor voltage or current and an error amplifier.

Filter inductors must be suitable for square waves at the

switching frequency (laminated steel is generally not ac-

ceptable). Filter capacitors must be low ESR and rated

for the expected ripple current. A difference amplifier with

gain of less than one translates the differential output voltage to a single feedback voltage. Dashed line connections

and a higher gain difference amplifier would be used for current control. The error amplifier integrates the difference

between the input and feedback voltages to close the loop.
