The MC34700 is a compact, high-efficiency power supply with on-chip
power MOSFETs that features three step-down switching regulators
and one low dropout linear regulator. The switching regulators utilize
voltage mode control with external compensation, allowing flexibility in
optimizing the performance of the 34700 for a given application.
The 34700 is ideal for space constrained applications where
multiple power rails are required and simplicity of design and
implementation of the power supply is necessary. Over-voltage,
under-voltage, over-current, and over-temperature protection
features ensure robust and reliable operation. Fixed switching
frequency, internal soft-start, and internal power MOSFETs enable
rapid 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.
