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. Description The SG3524 incorporates on a single monolithic chip all the function required for the construction of regulating power suppies inverters or switching regulators. They can also be used as the control element for high power-output applications. Philips Semiconductors Application note Applications using the SG3524AN126 1987 Feb2 APPLICATIONS The capacitor-diode output circuit is used in Figure 1 as a polarity converter to generate a -5V supply from +15V . This circuit is useful for an output current of up to 20mA with no additional boost transistors required. The first design below shows a straightforward low power boost converter circuit which uses the internal BJTs of the IC SG3524 for the switching, and therefore the maximum current is limited to 80 mA. This circuit can be used for converting any low voltage (above 5 V) to a desired higher level, across V O and GND.
