DESCRIPTION
This monolithic integrated circuit contains all the control circuitry for
a regulating power supply inverter or switching regulator. Included in
a 16-pin dual-in-line package is the voltage reference, error
amplifier, oscillator, pulse-width modulator, pulse steering flip-flop,
dual alternating output switches and current-limiting and shut-down
circuitry. This device can be used for switching regulators of either
polarity, transformer-coupled DC-to-DC converters, transformerless
voltage doublers and polarity converters, as well as other power
control applications. The SG3524 is designed for commercial
applications of 0
°
C to +70
°
C.
FEATURES
Complete PWM power control circuitry
Single ended or push-pull outputs
Line and load regulation of 0.2%
1% maximum temperature variation
Total supply current is less than 10mA
Operation beyond 100kHz
