APPLICATION INFORMATION (continued)
STANDARD CIRCUIT FOR FIXED VOLTAGE VERSION
CONVERTER FOR 0.7-V OUTPUT VOLTAGE
The TPS62050 is used to generate output voltages as low as 0.7 V. With such low output voltages, the inductor
discharges very slowly. This leads to a high output voltage ripple in power-save mode (SYNC = GND). It is
therefore recommended to use a larger output capacitor to keep the output ripple low. With an output capacitor of
47 μF, the output voltage ripple is less than 40 mV
PP
.
LAYOUT AND BOARD SPACE
All capacitors should be soldered as close as possible to the IC.
For information on the PCB layout see the user’s guideSLVU081
.
Keep the feedback track as short as possible. Any coupling to the FB pin may cause additional output voltage
ripple.
