资 源 简 介
The MC34700 is a compact, high-efficiency power supply with on-chippower MOSFETs that features three step-down switching regulatorsand one low dropout linear regulator. The switching regulators uTIlizevoltage mode control with external compensaTIon, allowing flexibility inopTImizing the performance of the 34700 for a given applicaTIon.The 34700 is ideal for space constrained applications wheremultiple power rails are required and simplicity of design andimplementation of the power supply is necessary. Over-voltage,under-voltage, over-current, and over-temperature protectionfeatures ensure robust and reliable operation. Fixed switchingfrequency, internal soft-start, and internal power MOSFETs enablerapid power supply design and development.The 34700 is well suited for power supply designs in wide variety of applications, including set top boxes, cable modems, laser printers, fax machines, point-of-sale terminals, small appliances, telecom line cards, and DVD players.
