Features:
Output current Max. 3A, long time working current: 2.1A.
Adopt new scheme design, using 2pcs large-sized solid ceramic capacitance.
Adopt high current shielding inductance and ultra-low resistance, maximize the conversion efficiency, reduce heat.
Ultra-compact size, perfect for the device where needs smaller space module such as RC aircraft, power bank, vehicle power.
High circuit conversion efficiency, the efficiency is up to 97.5% at 6.5V to 5V 0.7A, it reaches to 94% at 12V to 5V 1A.
Ultra-low quiescent current 0.85mA, no switch needed when connected to the car battery, can be connected to the cigarette lighter line, or ACC power line.
Output integrated adjustable and fixed voltage, fixed output directly solder the spot on board, and unusual voltage can be adjusted by potentiometer, very convenient.
