MC33470

The MC33470 is a digitally programmable switching voltage regulator, MC33470 is 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 5bit digitaltoanalog converter defines the dc output voltage.

MC33470 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.

MC33470 is ideally suited for computer, consumer, and industrial equipment where accuracy, efficiency and optimum regulation performance is desirable.
