Frequently Asked Questions
What is the switching frequency of the SG2524D?
The SG2524D supports a switching frequency of up to 450kHz, programmable via external resistor (RT) and capacitor (CT) components connected to the oscillator pins. This flexibility allows designers to optimize between switching losses and filter size in their SMPS designs.
What input voltage range does the SG2524D support?
The SG2524D operates over an input voltage range of 8V to 40V, with a nominal voltage of 20V. This wide range makes it suitable for industrial, telecom, and automotive-adjacent power supply applications where supply voltages may vary significantly.
What power supply topologies are compatible with the SG2524D?
The SG2524D features dual complementary output drivers, making it compatible with push-pull, half-bridge, and forward converter topologies. It can also be used in single-ended buck or boost converters when only one output is needed. This versatility covers a broad range of DC-DC conversion applications.
What package does the SG2524D come in and is it RoHS compliant?
The SG2524D is available in a 16-Pin Small Outline IC (SOIC) package, JESD-30 code R-PDSO-G16. It is RoHS/Pb-free compliant (JESD-609 code e4), suitable for use in environmentally regulated applications and modern manufacturing processes.
