Overview
MC33470 Synchronous Rectification DC/DC Converter Programmable Integrated Controller The MC33470 is a digitally programmable switching voltage regulator, specifically designed for Microprocessor supply, Voltage Regulator Module and general purpose applications, to provide a high power regulated output voltage using a minimum of external parts.
A 5−bit digital−to−analog converter defines the dc output voltage.
This product has three additional features.
The first is a pair of high speed comparators which monitor the output voltage and expedite the circuit response to load current changes.
The second feature is a soft−start circuit which establishes a controlled response when input power is applied and when recovering from external circuit fault conditions.
The third feature is two output drivers which provide synchronous rectification for optimum efficiency.
This product is ideally suited for computer, consumer, and industrial equipment where accuracy, efficiency and optimum regulation performance is desirable.
