POL power for advanced memories and ICs

Freescale Semiconductor has introduced two pairs of Point-Of-Load (POL) converters optimised for use with memory subsystems and microprocessors.

Each of the four devices features on-chip N-channel MOSFETs and integrated protection and output-monitoring features to minimise external components.

In memory applications, the MC34712 and MC34716 are able to supply the data-bus termination voltage and chipset reference voltage for DDR1/2/3 or other memory arrays. The MC34716 also has a 5.0A-rated output capable of providing the main supply voltage (VDDQ) to the memory-chipset.

The MC34713 and MC34717 are single- and dual-channel POL supplies with 5.0A continuous output per channel. These devices are used to convert an input voltage in the range 3.0V to 6.0V to an output in the range 0.7V to 3.6V to satisfy the core and I/O voltage requirements of processors and other advanced ICs. Voltage sequencing, tight output regulation, and the ability to track an external reference voltage when in a variety of configurations enable versatile performance in many single-supply applications.
