C Data signal

TP5

SCL: I

C Clock signal

TP6

SW: DC to DC converter switching node

TP7

INTB: Interrupt Signal

•

INTB = LOW: Interrupt detected

•

INTB = HIGH: No interrupt

TP8

PGND sense

TP9

PVIN Sense

TP10/TP11

Feedback loop for bode measurements (across R7)

TP12/TP13

VOUT: Output voltage sense (across C17)

TP14

Gate of the Q1 transistor used for Load Transient

TP15

AVIN Sense

TP16

Iout force

Setup

The following steps should be followed before the

Evaluation Board is operated

1. Install the Graphical User Interface (GUI)

Software on computer

2. Connect the Interface Board to the Board, using

the ribbon cable or board to board connectors

3. Connect Output Voltage and Loads (if any) to the

board

4. Configure all jumpers to Default Settings

5. Connect the interface board to computer with USB

cable

6. Connect NCV91300 Board 2.5 V~5.5 V (See

table 1) power supply to J3/J8 (J5) and J1/J8
connectors, pay attention to polarity of power
supply and the V clamp of the power supply.

7. Turn power supply on
8. Run the NCV91300 Graphical User Interface

Software
