■ GENERAL DESCRIPTION
the harmonic current resulting from the power supply block of
electrical devices.
current detector to ensure critical condition operation, a
transconductance error amplifier, high precision reference, a
current sensing comparator, and a totem pole output ideally suited
for driving a power MOSFET.
cycle-by-cycle overcurrent, and maximum peak current.
