The TPS63802 chip automatically transitions between modes, ensuring consistent 3.3V or 5V output from a lithium cell across its full discharge range (1.8V–5.5V input).\u003c\/p\u003e\n\u003ch4\u003eQ: Which output voltage should I select — 3.3V or 5V?\u003c\/h4\u003e\n\u003cp\u003eA: Choose 3.3V if you're powering microcontrollers like ESP32, STM32, or 3.3V sensors — this mode supports up to 2A output. Select 5V for Arduino boards, USB-standard devices, or peripherals that require 5V logic; this mode supports up to 1A. Check your device's datasheet to confirm its required supply voltage before connecting.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this module suitable for battery-powered and ultra-low-power applications?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. With a quiescent current as low as 20µA in 3.3V mode, the TPS63802-based module is designed for battery-powered applications where standby efficiency is critical. Its low quiescent draw helps extend the operational life of single-cell lithium batteries in IoT nodes, wearables, and other low-power embedded designs.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the PCB size and will it fit in compact enclosures?\u003c\/h4\u003e\n\u003cp\u003eA: The PCB measures just 10.4 × 7.9mm, making it one of the most compact buck-boost modules available. It is well-suited for integration into space-constrained enclosures, handheld devices, and wearable form factors.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
