描述 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 lockout 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.

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.

The TPQ05100x provides both adjustable voltage version

and fixed voltage version with DFN2X2-6 and WLCSP-6

packages.
