Description
AI
The TPS61322 is a synchronous boost converter with only 6.5-µA quiescent current. The TPS61322 provides a power-supply solution for products powered by alkaline battery, NiMH rechargeable battery, or one-cell Li-ion battery. The boost converter is based on a hysteretic control topology using synchronous rectification to obtain maximum efficiency at minimal quiescent current. The TPS61322 also allows the use of small external inductor and capacitors. Higher than 90% efficiency is achieved at 10-mA load from 1.5-V input to 2.2-V output conversion.
The TPS61322 can also support high output current applications with an external schottky diode. The TPS613222A provides higher than 500-mA output current capability at 3-V input voltage to 5-V output voltage conversion with an external Schottky diode in parallel with the internal rectifier FET.
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. Thus, it only needs two external components to get the desired output voltage. The TPS61322 also implements thermal shutdown protection function.
The TPS61322 is available in a 2.9-mm × 1.3-mm 3-pin SOT package or a 2.9-mm × 1.6-mm 5-pin SOT package.
