UG175: TS331x EVB User's Guide
The TS331x is a low power boost converter with an industry leading low quiescent cur-
rent of 150 nA, enabling ultra long battery life in systems running from a variety of bat-
tery sources. The TS331x steps up input voltages from 0.9 V to 5.0 V to eight selectable
output voltages ranging from 1.8 V to 5.0 V. The TS331x includes two output options,
one being an always-on storage output while the additional output is an output load
switch that is designed to burst-on loads in a low duty cycle manner.
The TS331x output voltage can be set via jumpers S0, S1, and S2. Both the STORE
and OUT output can be monitored along with the power good output VGOOD. Jumper
OUT_ON is available to disable or enable the OUT output.
