SG2524

The SG2524, and SG3524 incorporate on a single monolithic chip all the function required for the construction of regulating power suppies inverters or switching regulators. The SG2524 can also be used as the control element for high power-output applications. The SG2524 family was 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 techniques. The dual alternating outputs allows either single-ended or push-pull applications. The SG2524 includes an on-ship reference, error amplifier, programmable oscillator, steering flip flop, two uncommitted output transistors, a high-gain comparator, and currentlimiting and shut-down circuitry.
