2.1
Evaluation With the TPS6103x EVM
This chapter details the evaluation process and features of the EVM. For
detailed evaulation, a load must be connected to the output terminal in order
to adjust the load current between 0 mA and 1600 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 eliminates 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) Jumper
This jumper is used to enable the device. Connecting the enable pin (EN) to
V
BAT
enables the part. The device is disabled when EN is set to GND. For more
details refer to the data sheet.
2.1.2
Power Save Mode Enable and Synchronization (SYNC) Jumper
This jumper enables the device to enter into power save mode at light load,
when it is set to GND. 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 V
BAT
, the
device stays operating in fixed frequency mode, regardless of the load current
value. In this mode, however reverse current flows back to the input during light
load operation, increasing power losses. The operating frequency stays
constant, which implies low output voltage ripple.
To synchronize the operating frequency to an external frequency, a clock
signal can be applied to the SYNC pin. The device then operates at the applied
operating frequency, with no Power Save Mode. For more details about the
applied frequency and the synchronization frequency range, refer to the
device data sheet.
2.1.3
LBI/LBO Comparator
The LBO terminal is an open drain output and has a pullup resistor, R6,
connected to the output. The signal on this pins goes low as soon as the input
voltage at LBI falls below the threshold of 500 mV. Refer to the more detailed
description in the data sheet. The LBO output stays at high-impedance when
the input voltage at LBI is above the appropriate threshold. A resistor divider
(R1, R2) is used on the EVM to monitor the supply voltage.
More details about setting the low battery threshold voltage can be found in
the data sheet (SLVS534).
