TPS61282D
- 95% efficiency at 2.3 MHz operation
- 3-µA quiescent current in low I Q pass-through mode
- Wide V IN range from 2.3 V To 4.8 V
- I OUT ≥ 4-A (Peak) at V OUT = 3.35 V, V IN ≥ 2.65 V
- Integrated pass-through mode (35 mΩ)
- Programmable valley inductor current limit and output voltage
- True pass-through mode during shutdown
- Best-in-class line and load transient
- Low-ripple light-load PFM mode
- In-Situ customization with On-Chip E 2PROM (write protection)
- Two interface options:
- I 2C compatible I/F up to 3.4 Mbps (TPS61280D/E)
- Simple I/O logic control interface
- Thermal shutdown and overload protection
- Total solution size < 20 mm 2, sub 1-mm profile
The TPS6128xD/E device provides a power supply solution for products powered by either by a Li-Ion, Nickel-Rich, Silicon Anode, Li-Ion or LiFePO4 battery. The voltage range is optimized for single-cell portable applications like in smart-phones or tablet PCs.
Used as a high-power pre-regulator, the TPS6128xD/E extends the battery run-time and overcomes input current- and voltage limitations of the powered system.
While in shutdown, the TPS6128xD/E operates in a true pass-through mode with only 3-µA quiescent consumption for longest battery shelf life.
During operation, when the battery is at a good state-of-charge, a low-ohmic, high-efficient integrated pass-through path connects the battery to the powered system.
If the battery gets to a lower state of charge and its voltage becomes lower than the desired minimum system voltage, the device seamlessly transits into boost mode to uses the full battery capacity.
