SOFTWARE GUI

The DC1577A Demo Circuit can be controlled from a

software GUI.

Most of the features of the

LTC3576EUFE-1 are only accessible via the I2C chan-

nel. When the QuikEval program is active and a

DC590 with a DC1577A connected and attached to

the USB cable, the “LTC3576” form should auto-

matically pop up and be fully operational:

SOFTWARE OPERATION

The software GUI automatically opens the control

panel shown above. This control panel allows con-

trol of most major functions of the LTC3576EUFE-1.

The EN1, EN2, EN3, and ENOTG signals are wire

OR’ed with individual regulator enable regulator sig-

nals from the I2C channel. Consequent to this, if

the ENx or ENOTG signals are high, the regulators

will be enabled regardless of the state of the I2C

channel regulator control bits.

These are not writeable and are provided as a pro-

gramming aid. The current value of the I2C A, B, C

and D registers are displayed.

Update button

Forces an immediate update of the I2C registers.
