3 Description
The TPS61299 is a synchronous boost converter with
95-nA ultra-low quiescent current and average input
current limit. The device provides a power solution
for portable equipment with alkaline battery and coin
cell battery. This device has high efficiency under
light-load condition to achieve long operation time
and average input current limit can avoid battery
discharging with high current.
The TPS61299 has wide input voltage range from 0.5
V to 5.5 V and output voltage range from 1.8 V to
5.5 V. The device has different versions for average
input current limit from 5 mA to 1.9 A. The TPS61299
with 1.2-A current limit can support up to 500-mA
output current from 3-V to 5-V conversion and achieve
approximately 94% efficiency at 200-mA load.
The TPS61299 has optional fast-load transient
performance at output voltage is 4.5 V, 5 V or 5.5 V.
In fast-load transient, the typical setting time is 8 μs
when output current transient from 0 A to 200 mA.
The TPS61299 supports optional force pass through
or true shutdown function when it is disabled, which is
flexible for always-on system.
The TPS61299 offers a very small solution size with
6-ball 1.2-mm x 0.8-mm WCSP package and 6-pin
1.6-mm x 0.6-mm SOT563 package.
