DESCRIPTION
The TS3310 is a low power boost switching regulator
with an industry leading low quiescent current of
150nA. The 150nA is the actual current consumed
from the battery while the output is in regulation. The
TS3310’s extremely low power internal circuitry
consumes 90nA on average, with periodic switching
cycles which service the load occurring at intervals of
up to 25 seconds, together yielding the average
150nA. The TS3310 steps up input voltages from
0.9V to 3.6V to eight selectable output voltages
ranging from 1.8V to 5V. The TS3310 includes two
output options, one being an always-on storage
output while the additional output is an output load
switch that is designed to supply burst-on loads in a
low duty cycle manner. The TS3310 operates in
Discontinuous Conduction Mode with an on-time
proportional to 1/VIN, thereby limiting the maximum
input current by the selection of the inductor value,
ensuring the input current does not drag down the
input source.
The extremely low quiescent current combined with
the output load switch make the TS3310 an ideal
choice for applications where the load can be
periodically powered from the output, while being
disconnected from the output storage capacitor when
the load is powered off to isolate the load’s leakage
current.
The TS3310 is fully specified over the -40°C to +85°C
temperature range and is available in a low-profile,
thermally-enhanced 10-pin 2x2mm TDFN package
with an exposed back-side paddle.
