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.
