SG2524, SG3524
SLVS077E – APRIL 1977 – REVISED JANUARY 2015
SGx524 Regulating Pulse-Width Modulators
1 Features
•1 Complete Pulse-Width Modulation (PWM) Power-
Control Circuitry
• Uncommitted Outputs for Single-Ended or Push-
Pull Applications
• 8 mA (TYP) Standby Current
2 Applications
• Transformer-coupled DC/DC convertors
• Switching-regulators of any polarity
3 Description
The SG2524 and SG3524 devices incorporate all the
functions required in the construction of a regulating
power supply, inverter, or switching regulator on a
single chip. They also can be used as the control
element for high-power-output applications. The
SG2524 and SG3524 were designed for switching
regulators of either polarity, transformer-coupled dc-
to-dc converters, transformerless voltage doublers,
and polarity-converter applications employing fixed-
frequency, pulse-width modulation (PWM)
techniques. The complementary output allows either
single-ended or push-pull application. Each device
includes an on-chip regulator, error amplifier,
programmable oscillator, pulse-steering flip-flop, two
uncommitted pass transistors, a high-gain
comparator, and current-limiting and shutdown
circuitry.
