The 34700 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.

Channel 1 of the 34700 can operate from an input voltage of 9V to 18 V, while Channels 2, 3, and 4, operate from a voltage input of 1.5 V to 6 V. Channels 2 and 3 can derive their input supplies from the output of Channel 1 or from an external bias voltage, while Channel 4 can derive its input supply from any of the outputs of Channels 1 through 3 or from an external bias voltage.

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. Overvoltage, undervoltage, overcurrent, and overtemperature protection features ensure robust and reliable operation. Fixed switching frequency, internal soft-start, and internal power MOSFETs enable rapid power supply design and development.
