🔌 The Problem: Powering Smart Glasses Efficiently

Smart glasses are packed with features—cameras, displays, sensors—all running on a compact low-voltage battery. But if not regulated properly, even a slight voltage drop can crash the system or shorten component life. Power stability is critical in wearables.

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

To keep your smart glasses running smoothly, use a Low Dropout Regulator (LDO) for clean voltage output, or a boost converter to step up small lithium battery voltages. These ensure stable operation even as the battery depletes. Add a reverse polarity diode for added protection.

🔍 Practical Example :

Say your smart glasses run on a 3.7V Li-ion cell, but the onboard camera needs 5V. Using a small boost converter like the MT3608 can easily step up 3.7V to 5V. Add a Schottky diode to protect against accidental reverse battery connection.

📐 Sample Calculation :

For a 5V, 300mA load:

Power Output = 5V × 0.3A = 1.5W

Assuming 85% efficiency,

Input Power = 1.5W / 0.85 ≈ 1.76W

Input Current at 3.7V = 1.76W / 3.7V ≈ 0.48A

Choose a converter rated for at least 0.6A for safe operation.
