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 F, the output voltage ripple is less than 40 mVPP.
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.
