Features:
1. Very few peripheral components, only one inductor is needed, easy to produce
2. High efficiency: 85~90% (typical value), can make full use of solar cells to adjust current through inductance,
Simple and convenient, stable current, good consistency, input current is not affected by LED turn-on voltage
3. Low enable voltage, ensure that the lamp is turned on only when the external light is dark enough
4. Enable control has Schmitt performance, ensuring the stability of the lamp when switching between light and dark
