n GENERAL DESCRIPTION

The

SS6341

combines

a

synchronous

voltage-mode PWM controller with two linear

controllers, including the associated monitoring and

protection functions. It is able to power CPUs, GPUs,

memories, chipsets and multi-voltage applications.

The PWM controller regulates the output voltage

using a synchronous rectified step-down converter.

The built-in N-Channel MOSFET drivers also help to

simplify the design of the step-down converter. The

PWM controller features over-current protection

using

the

RDS(ON) of the external MOSFET,

improving efficiency and cost, as there is no

expensive current sense resistor required.

Two built-in adjustable linear controllers drive

external MOSFETs to form two linear regulators that

regulate power for multiple system I/Os. The output

voltage of both linear regulators can also be

adjusted by means of an external resistor divider.

Both linear regulators feature current-limiting. For

system I/Os requiring current less than 500mA, the

SS6340 is recommended as it saves one

external MOSFET.

The programmable soft-start design provides a

controlled output voltage rise, which limits the

current during power-on.

A shutdown function is also provided, for disabling

the combo controller.
