The TPS61322x is a synchronous boost converter with only 6.5-µA quiescent current.
TPS61322x provides a power-supply solution for products powered by alkaline battery, NiMH
rechargeable battery, or one-cell Li-Ion battery. The minimum current limit is 0.45 A for TPS61322,
0.6 A for TPS613221 and 1.2 A for TPS613222. The boost converter is based on a hysteretic control
topology using synchronous rectification to obtain maximum efficiency at minimal quiescent
currents. Higher than 85% efficiency can be achieved at 10mA load from 1.2-V input to 2.2-V output.
TPS61322x can also support non-synchronous operation for high output load applications.
The TPS613222 provides higher than 500 mA output current capability at 3.0 V input voltage to 5.0 V
output voltage conversion with an external Schottky diode in parallel with the internal rectifier
The output voltage is set internally to a fixed output voltage from 1.8 V to 5.5 V in
increments of 0.1 V. TPS61322x is packaged in a 2.9-mm × 1.3-mm 3-pin SOT package.
