TPS61088A Single Cell Lithium Battery Boost Module - 24W QC3.0 Fast Charge

Specifications

• Main Control IC: TPS61088A

• Input Voltage: 2.8V to 4.5V

• Output Voltage: Adaptive 5V, 9V, 12V

• Max Output Power: 24W.

• Output Current: 5V @ 3A, 9V @ 2A, 12V @ 2A (Adaptive).

• Efficiency: Up to 91% (At high load).

• Features: Soft-start, programmable peak current limit, thermal shutdown.

Key Applications & Projects

• DIY Fast Charge Power Banks: Build a high-capacity portable charger for modern phones.

• Portable IoT Gateways: Powering 12V routers or 5V Raspberry Pi systems from a single battery.

• Outdoor Lighting: Boosting 3.7V to 12V for high-brightness LED arrays.

• Field Equipment: Providing stable 9V or 12V rails for sensors from portable battery packs.

Project Evolution

• Past Projects (Prerequisites): If you've used the MT3608 or XL6009 and found them too weak for charging phones or powering 12V 2A loads, this is your upgrade.

• Feature Upgrade: This module unlocks Intelligent Handshaking. It communicates with the connected device to negotiate the highest possible voltage (up to 12V) safely, something standard boost modules cannot do.

• Effort/Requirements: Intermediate. Requires high-quality lithium batteries (high discharge rate) and proper 18AWG wiring to handle the high input currents (up to 7A+ peak at the battery side).

Virtual Technician & Wiring

⚠️ Safety Warning: This module draws significant current from the battery. Use thick wires and ensure your lithium cell is rated for at least 10A continuous discharge to avoid fire hazards.

Package Includes: 1 x TPS61088A Single Cell Lithium Battery Boost Module

Frequently Asked Questions (FAQ)

• Can I use this with two batteries in series? No, this is for a single cell (3.7V). Max input is 4.5V.
• Does it support iPhone fast charging? It supports DCP and QC protocols; iPhones typically use USB-PD, but will charge at standard 5V 2.4A high-speed rates.
• What is the maximum current it can pull from the battery? At 24W output, it can pull over 7A-8A from a 3V battery. Use high-discharge cells.
• Does it get hot? At 24W, the chip will get hot. Ensure proper airflow in your enclosure.
• Is the output voltage adjustable? No, it is adaptive based on the fast charge protocol of the connected device.
• Can I use it to power an Arduino? Yes, it will default to 5V if no fast charge protocol is detected.
• Does it have battery protection (BMS)? No, it is a boost converter. You must use a separate BMS or protected lithium cells.
• What happens if I reverse the input? Reversing the input will destroy the TPS61088A chip immediately.
• What is the idle current? Very low, typically in the microamp range in shutdown, but check your specific circuit for quiescent draw.
• Can it boost to 12V from a nearly empty battery? Yes, it operates down to 2.8V, though efficiency drops at lower voltages.
• Is it original TI silicon? We source verified, high-grade TPS61088A modules to ensure rated power delivery.
• What wire should I use for input? Use at least 20AWG or 18AWG for the battery connections.
• Can it charge a laptop? Only if the laptop supports 12V USB charging (rare). Most laptops require 20V USB-PD.
• What is the ripple voltage? Very low due to the high-frequency switching design.
• Does it support Samsung Adaptive Fast Charging? Yes, it is compatible with most QC-based adaptive protocols.
• Is there a USB port on it? Most PRO1507 variants come with a pre-soldered USB-A female port.
• Can I parallel two of these for 48W? Not recommended; the protocols may conflict.
• Does it have a soft-start feature? Yes, it prevents huge inrush currents from the battery.
• What is the switching frequency? Typically around 500kHz to 1MHz (Internal TI spec).
• Can I use it for a lead-acid battery? No, the voltage range (9V-12V) of a lead-acid battery is too high for the input.
