TPQ05100x
0.9-V to 5.5-V VIN, 600-mA Synchronous Step-up Regulator
Features
Description
The TPQ05100x series of products are synchronous
boost converters with less than 260-nA ultra-low quiescent
current. The device has an ultra-low under-voltage lock-
out threshold to support different kinds of battery voltages
as low as 0.9 V. The ultra-low 260-nA quiescent current
increases light load efficiency and thus increases battery
life.

The TPQ05100x series of products have various voltage
options to support fixed output voltage ranging from 2.5 V
to 5 V, and adjustable output voltage ranging from 2.5 V to
5.5 V. The device has a true-shutdown feature that avoids
leakage current during the shutdown mode to further save
system level quiescent current.
True Disconnection During Shutdown
Up to 80% Efficiency at 10-μA Load with Fixed Output
Voltage Versions
Up to 96% Efficiency from 10-mA to 300-mA Load

WLCSP-6, DFN2X2-6 packages
The TPQ05100x series provides the down mode and the
pass-through mode to support different scenarios. In the
down mode, the device can still regulate output voltage to
a desired level. In the pass-through mode, the TPQ05100x
devices work as switches that the output voltage follows
input voltage.
