TPS6128x Low-, Wide- Voltage Battery Front-End DC/DC Converter

Single-Cell Li-Ion, Ni-Rich, Si-Anode Applications

1 Features

3 Description

The TPS6128x 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.

•

95% Efficiency at 2.3MHz Operation

2µA Quiescent Current in Low I_QPass-Through

Mode

•

Wide V_INRange From 2.3V to 4.8V

I_OUT≥ 4A (Peak) at V_OUT= 3.35V, V_IN≥ 2.65V

Used as a high-power pre-regulator, the TPS6128x

extends the battery run-time and overcomes input

current- and voltage limitations of the powered

system.

Integrated Pass-Through Mode (35mΩ)

Programmable Valley Inductor Current Limit and

Output Voltage

While in shutdown, the TPS6128x operates in a true

pass-through mode with only 2µA quiescent

consumption for longest battery shelf life.

•

Programmable Average Input 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 E²PROM

(Write Protect)

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 utilize the full battery capacity.

•

Two Interface Options:

–

I²C Compatible I/F up to 3.4Mbps (TPS61280)

Simple I/O Logic Control Interface (TPS6128x)

•

Thermal Shutdown and Overload Protection

Total Solution Size <20mm², Sub 1-mm Profile
