Brand: QSKJ
Model: QS-1205CME-3A
Two Types of Inductors, Same price, same quality. If not specified, we will ship randomly.
Features:
- With a new original US chip, the output current is up to 3A, and the long-term operation is 2.1A. Output can be set to adjustable voltage and fixed voltage.
- With a new solution design, the circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitors have a short lifetime and the tantalum capacitors are in danger of explosion).
- The new scheme adopts synchronous rectification, and the circuit conversion efficiency is very high. When the 6.5V to 5V 0.7A, the efficiency is as high as 97.5%, and when 12V turns 5V 1A, it also reaches 94%.
- High current shielding inductors and ultra-low internal resistance maximize conversion efficiency. Reduce heat.
- Mini, 20 (L) * 11 (W) * 5 (H) mm. Ultra-low static current, static current 0.85 mA. Connecting to car batteries without switching, can be on the cigarette lighter line, or on the ACC power line.
