MODES OF OPERATION

The 34716 has three primary modes of operation:

Normal Mode

In normal mode, all functions and outputs are fully

operational. To be in this mode, the V IN needs to be within its

operating range, both Shutdown and Standby inputs are

high, and no faults are present. This mode consumes the

most amount of power.

Standby Mode

This mode is predominantly used in Desktop memory

solutions where the DDR supply is desired to be ACPI

compliant (Advanced Configuration and Power Interface).

When this mode is activated by pulling the STBY pin low, V TT

is put in High Z state, I OUT2 = 0 A while V DDQ and V REF stay

active. This is the S3 state Suspend-To-Ram or Self Refresh

mode and it is the lowest DRAM power state. In this mode,

the DRAM will preserve the data. While in this mode, the

34716 consumes less power than in the normal mode,

because the buck converter and most of the internal blocks

are disabled.

Shutdown Mode

In this mode, activated by pulling the SD pin low, the chip

is in a shutdown state and the outputs are all disabled and

discharged. This is the S4/S5 power state or Suspend-To-

Disk state, where the DRAM will loose all of its data content

(no power supplied to the DRAM). The reason to discharge

the V TT and V REF lines is to ensure upon exiting, the

shutdown mode that V TT and V REF are lower than V DDQ ,

otherwise V TT can remain floating high, and be higher than

V DDQ upon powering up. In this mode, the 34716 consumes

the least amount of power since almost all of the internal

blocks are disabled.

START-UP SEQUENCE

When power is first applied, the 34716 checks the status

of the SD and STBY pins. If the device is in a shutdown mode,

no block will power up and the output will not attempt to ramp.

If the device is in a standby mode, only the V DDI internal

supply voltage and the bias currents are established and no

further activities will occur. Once the SD and STBY pins are

released to enable the device, the internal V DDI POR signal is

also released. The rest of the internal blocks will be enabled,

and the buck converters switching frequency and the V DDQ
