JAJSH60A april 2019 – december 2020 UC1825B-SP
PRODUCTION DATA
The UC182B-SP is designed to operate from an input voltage supply range between 10 V and 30 V. This input supply should be well regulated. If the input supply is located more than few inches from the UC1825B-SP converter, additional bulk capacitance may be required in addition to the ceramic bypass capacitors. A tantalum capacitor with a value of 100 μF is a typical choice; however, this may vary depending upon the output power being delivered.
The UC1825B-SP controller can be used to convert power efficiently using any of several standard topologies such as push-pull, forward, half-bridge, or full bridge. Design tradeoffs of cost, size, and performance narrow the field to the one that is most appropriate. For a typical application, such as in Section 8.2, push-pull converter topology is highlighted.
