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.

MC33470 Features:
• 5–Bit Digital–to–Analog Converter Allows Digital Control of Output Voltage
• High Speed Response to Transient Load Conditions
• Output Enable Pin Provides On/Off Control
• Programmable Soft Start Control
• High Current Output Drives for Synchronous Rectification
• Internally Trimmed Reference with Low Temperature Coefficient
• Programmable Overcurrent Protection
• Overvoltage Fault Indication
• Functionally Similar to the LTC1553
