Freescale Semiconductor

Advance Information

5.0 A 1.0 MHz Fully Integrated

Single Switch-Mode Power

Supply

34713

The 34713 is a highly integrated, space efficient, low cost, single

synchronous buck switching regulator with integrated N-channel

power MOSFETs. It is a high performance point-of-load (PoL) power

supply with the ability to track an external reference voltage in

different configurations.

SWITCH-MODE POWER SUPPLY

Its high efficient 5.0 A continuous output current capability

combined with its voltage tracking/sequencing ability and tight output

regulation, makes it ideal as a single power supply.

The 34713 offers the designer the flexibility of many control,

supervisory, and protection functions to allow for easy implementation

of complex designs. It is housed in a Pb-Free, thermally enhanced,

and space-efficient 24-Pin Exposed Pad QFN.
