Evaluation With the TPS6110x EVM

2.1
Evaluation With the TPS6110x EVM
This chapter details the evaluation process and features of the EVM. For this
evaluation, a load is connected to the output terminal in order to adjust the load
current between 0 mA and 250 mA.
For accurate output voltage and input voltage measurements, it is important
to measure the voltage on the input and output voltage terminals with Kelvin
contacts or with a voltmeter connected directly to the input voltage or output
voltage terminals. This will eliminate any measurement errors related to
voltage drops along the input and output terminal wires connected to the
power supply or load.
2.1.1
Enable (EN) and Enable Pushbutton (ENPB) Jumper
These jumpers are used to enable the device. Connecting the enable pin (EN)
to V
BAT
or connecting the enable pushbutton (ENPB) to GND enables the part.
The device is only disabled when ENPB is set to V
BAT
and EN is set to GND.
Both enable pins are used to implement enable with a pushbutton and a static
signal for example from a microcontroller. For more details refer to the data
sheet.
2.1.2
LDO Enable (LDOEN) Jumper
This jumper is used to enable the integrated LDO of the device. Connecting
the LDO enable pin (LDOEN) to V
BAT
enables the LDO section of the part.
Disabling the integrated LDO can be done by setting this jumper to GND.
2.1.3
Auto Discharge Enable (ADEN) Jumper
This jumper enables the device to discharge the output capacitor after the
device is disabled by setting EN to GND. If ADEN is set to V
BAT
, the capacitors
connected to V
OUT
is discharged by an internal switch with a resistance of
about 400
. The discharge time depends on the total output capacitance. The
residual output voltage is less than 0.4V after auto discharge.
When disabling the auto discharge function by setting the jumper to GND, the
output capacitors will only be discharged by the load and/or by the leakage
currents in every connected part.
2.1.4
Power Save Mode Enable (SKIPEN) Jumper
This jumper enables the device to enter in power save mode at light load, when
it is set to V
BAT
. The device automatically stops switching when the output
voltage reached its upper threshold, and starts switching again, when the
lower threshold of the output voltage is reached.
When disabling the power save function by setting the jumper to GND, the
device stays operating in fixed frequency mode, regardless of the load current
value. In this mode, however reverse current will flow back to the input during
light load operation increasing power losses. The operating frequency stays
constant, which implies low output voltage ripple.
