TPS61088A 24W Quick Charge Boost Converter Module
The TPS61088A 24W Quick Charge Boost Converter Module is a high-power DC-DC step-up converter designed for single-cell lithium-ion and lithium-polymer battery applications. It can boost a low battery voltage to 5V, 9V, or 12V and is suitable for DIY power banks, portable chargers, embedded electronics, IoT projects, and battery-powered devices.
The module is based on the TPS61088 high-current synchronous boost converter. Texas Instruments specifies the TPS61088 for 2.7V to 12V input operation, 4.5V to 12.6V output capability, 10A switch current, synchronous rectification, programmable current limiting, overvoltage protection, overcurrent protection, and thermal shutdown.
For this particular 24W Quick Charge module, typical module specifications are 2.8V–4.5V input, 5V/3A, 9V/2A or 12V/2A output, with support for QC2.0, QC3.0, Huawei FCP and DCP charging protocols.

The IC itself has a broader specification than this particular module. For example, TI specifies 2.7V–12V input and 4.5V–12.6V output for the TPS61088, while the commercially available 24W module is designed around a much narrower battery input range.
How TPS61088A Boost Module Works
A single lithium battery normally provides around 3.7V nominal voltage. The TPS61088A boost converter increases this voltage to a higher regulated voltage.
For example:
3.7V battery → TPS61088A → 5V / 9V / 12V output
When a compatible fast-charging device is connected, the module can negotiate an appropriate charging voltage through its supported charging protocol. This makes it useful for DIY power banks and portable USB power solutions. The TPS61088 itself uses synchronous rectification and peak-current control for high-power-density boost conversion.
Applications:
This module is suitable for:
- DIY USB power bank
- 18650 battery power bank
- Li-ion battery charger projects
- Li-Po battery projects
- Portable USB power supply
- QC3.0 fast-charging projects
