Setup and Results
2.1.5
J5 – VOUT Sense / GND Sense
Header J5 can be used to measure the output voltage directly on the output capacitor.
2.1.6
J6 – GND
This header is the return connection of the output voltage. Connect the load between J6 and J4 (VOUT).
2.1.7
J7 – EN
This jumpers enables/disables the TPS63036 on the EVM. The shorting jumper J7 between the center pin
and ON turns on the unit. Shorting the jumper between center pin and OFF turns the unit off. A 1-M
and ON turns on the unit. Shorting the jumper between center pin and OFF turns the unit off. A 1-M
Ω
pullup resistor is connected between VIN and EN. Removing the jumper J7 turns on the converter.
2.1.8
J8 –PS/SYNC
The center pin of this jumpers is connected to the SYNC pin of the TPS63036 and is used to synchronize
the unit with an external clock. This jumper also enables/disables the power-saving mode at light loads.
Shorting jumper J8 between the center pin and PWM disables the power-saving mode; the jumper
between the center pin and PWM/PSM enables the power-saving mode. The device operates in power-
saving mode at light-load conditions. See the TPS63036 data sheet (

Setup
To operate the EVM, simply connect an input supply between J1 and J3. Connect a load between J4 and
J6. Input supply voltage of 1.8-V to 5.5-V is recommended.

2.3
Power Up
After the device is enabled and starts operating the average switch current limit is ramped up from initial
400mA following the output voltage increasing. At an output voltage of 1.2-V, the switch current limit is at
its nominal value of 1000-mA. If the output voltage does not increase, the switch current limit does not
increase.
