🕶️ The Problem: Powering Smart Glasses at Low Voltage

Designing smart glasses requires a compact, energy-efficient power supply that can operate reliably at low voltage, typically between 3.3V to 5V. These devices often incorporate sensors, displays, and Bluetooth modules—all of which need stable power. Using a bulky regulator or inefficient converter can lead to overheating or quick battery drain.

🔧 The Solution: Use a Low Dropout Regulator or Boost Converter

To power smart glasses efficiently, use a Low Dropout Regulator (LDO) when the input is slightly higher than the output, or a Boost Converter when using small Li-ion cells (like 3.7V) to power 5V circuits. These solutions ensure steady performance and long battery life without overheating the frame.

🔋 Practical Example :

Let’s say you’re using a 3.7V Li-ion battery to run a 5V display and a microcontroller. A tiny boost converter like the MT3608 can lift the voltage to 5V, while still fitting in the slim body of smart glasses.

🧮 Sample Calculation :

If your circuit consumes 200mA at 5V, required power is:

P = V × I = 5V × 0.2A = 1W

Assuming 85% efficiency:

Input power ≈ 1W / 0.85 = 1.18W

At 3.7V: I ≈ 1.18W / 3.7V ≈ 319mA
