MC34700 removed from active portfolio. Possible Replacement Part: PF3000.

The NXP^® 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 use voltage-mode control with external compensation, allowing flexibility in optimizing the performance of the MC34700
Ideal for space-constrained applications where multiple power rails are required and simplicity of design and implementation of the power supply is necessary
Protection features ensure robust and reliable operation
Fixed switching frequency, internal soft-start, and internal power MOSFETs enable rapid power supply design and development
