Frequently Asked Questions
Q: What input voltage range does the TPS63802 boost module support?
A: The TPS63802 boost module accepts a DC input voltage range of 1.8V to 5.5V, making it fully compatible with single-cell lithium batteries (typically 3.0–4.2V), AA/AAA battery packs, and other low-voltage sources.
Q: Can I switch between 3.3V and 5V output on the same module?
A: The output voltage (3.3V or 5V) is typically selected at the hardware level via a solder pad or pin configuration on the PCB. Please check the module's silkscreen or datasheet for the exact switching method. Note that the 3.3V variant supports up to 2A output, while the 5V variant supports up to 1A.
Q: Is this module suitable for Arduino or ESP32 projects?
A: Yes! The TPS63802 boost module is an excellent power solution for Arduino, ESP32, Raspberry Pi Zero, and similar microcontroller boards. The 3.3V/2A mode is ideal for ESP32 and sensor arrays, while the 5V/1A mode suits Arduino Uno and USB-powered peripherals.
Q: How does the low quiescent current benefit battery-powered designs?
A: With a quiescent current of just 20–30µA at 3.7V input, the module draws minimal power when the load is idle or in sleep mode. This significantly extends battery life in low-duty-cycle applications such as IoT sensors, remote devices, and portable instruments.
