Adopt flow expansion MOS tube.The output current is expanded to the rated 1A, which can output as much as 1.5A, using 2A Schottky diodes, and the balance is recharged.The circuit design does not require electrolytic capacitors and tantalum capacitors (the life of electrolytic capacitors is short, and tantalum capacitors may explode). Three ceramic capacitors currently used in high-end circuits are used.The ripple is very low, only tens of millivolts, and many of the ripples in the industry have reached 500 millivolts, which will cause an invisible damage to the equipment, and severely cause the equipment to work abnormally or damage.The same load indicator light and undervoltage indicator (when the battery voltage is less than 2.7V, the indicator light will go out under load, when the battery voltage is greater than 2.7V, the indicator light will be on when the battery voltage is greater than 2.7V, and the indicator light will be slightly off when there is no load. bright)The circuit conversion efficiency is high. When the efficiency is high, it exceeds 90%. The efficiency of a single-cell lithium battery is also greater than 80%. Unlike some of the counterparts, the efficiency is only 60-70%.Input low power reverse connection protection, if your battery has a 2A protection board, the protection board will protect when the positive and negative poles of the input power supply are reversed. Note that when there is no protection board or the input current is greater than 2A, the input reverse connection protection It will fail and cause damage to the module, remember.Low quiescent current, the new version, the quiescent current will be less than 100 microamperes. No switch is required to connect to the battery.Material:pcbcolour:greenPackage Contents:1 * boost moduleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
