Setup
This is the return connection for the VLDO2 output rail.
This is the positive output for the VLDO3 LDO linear regulator. This output is input programmable for the
TPS65050 and TPS65052 and externally adjustable for the TPS65051, TPS65054 and TPS65056. The
VLDO3 output is capable of supplying up to 200 mA. The EVM preset output voltages are found in
TPS65050 and TPS65052 and externally adjustable for the TPS65051, TPS65054 and TPS65056. The
VLDO3 output is capable of supplying up to 200 mA. The EVM preset output voltages are found in

Pin 1 of this output allows the user to measure the PB_OUT (TPS65050) or RESET (TPS65051/
TPS65052/ TPS65054/ TPS65056) output. The PB_OUT output is toggled using the SW1 pushbutton
switch. The RESET output goes high 100 ms after the THRESHOLD input exceeds 1 V. RESET goes low
when the HYSTERESIS input falls below 1 V. On the EVM, the RESET circuitry monitors the input
voltage. The rising threshold is set to a 3.4-V input and the falling threshold is set to 3.3 V.

JP1 is used to enable the VDCDC1 output. Place a shorting bar in the ON position to turn on the VDCDC1
step-down converter. Place a shorting bar in the OFF position to turn off the VDCDC1 converter.

JP2 is used to select between the forced PWM and Power Save mode operation for the switching
converters. Place a shorting bar in the PSM position to select the Power Save mode. In this mode, PFM is
used for light loads, and PWM is used for heavier loads. Place a shorting bar in the PWM position to force
PWM operation at all loads.

JP3–JP6 are used to program the LDO regulation voltages for the TPS65050 and TPS65052. Place a
shorting bar in the HI position to connect DEFLDO1 to the input voltage. Place a shorting bar in the LO
position to connect DEFLDO1 to GND. This jumper is not installed on the TPS65051, TPS65054 and
TPS65056 EVMs.
