IC program, the main chip models (MIP0222) circuit performance
Input characteristics
Input current is 0.422 (AC110V) -0.163 (AC220V) A (under full load)
PCB size: 17.55mm * 25.22mm * was 5.85 mm and (no usb the height)
En bloc Size: 17.55 * 32.53mm * 8.3mm (with usb height)
1. input any DC voltage of 1V ~ 5V, output 5V DC voltage is stable, the input to the output current of 500 ~ 600MA with two AA batteries, a single AA battery power supply output current 200ma about for mobile phones camera, single-chip, digital products supply.
2. with USB female versatile
3. high conversion efficiency, up to 96%
4. ultra-small size, installed in a variety of small equipment
6. Led indicator- red is charging Green is full charged.
7. Input interface- mini USB.
8. Work temperature- -10℃ to +85℃.
9. Inversed polarity- NO.
10.Size- small to 25X19X10mm.
NOTE:
1. Ampere meter can only be connected to 5v input end of the module.
2. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip.
Как утверждает информация, нанесенная на аккумулятор, в него встроена плата управления, способная отключить батарею в случае короткого замыкания, переразряда и перезаряда.
Реальная емкость сильно меньше указанной на самом аккумуляторе.
The switching power supply circuit board temperature protection, over current and short circuit protection, AC90 ~ 240V wide voltage input, DC3V-25V output, input to output isolation, small size, 431 precise regulation, quality assurance.
Данный адаптер не выдает заявленную мощность (вот хороший адаптер), а преимущество его в том, что он не заклеен и легко разбирается. Внутри установлена плата, которую можно вынуть и заменить на свою, либо просто усовершенствовать оригинальную - подогнать под свои нужды.
Интерес данный адаптер представляет для тех, кто собирается его модифицировать или использовать его корпус для свои разработок.
This Lithium ion battery protection PCB protect single Lithium ion batteries. 4A continous current
Lithium ion protection is necessary, as Lithium ion will explode when they are shorted circuit or overcharged, and damaged when they are over discharged.
After Lithium ion is connected to the PCB, the board protect individual batteries from:
1. Over charging - Disconnect circuit when either battery is over 4.25V
2. Over discharging - Disconnect circuit when either battery is lower than 2.5V
3. Short curcuit protection - Disconnect when short circuit is detected
Connection:
B+ - TO +ve of the battery
B- - TO -ve of the battery
P+ - TO +ve of load/input
P- - TO -ve of load/input
Protection IC: 100B
Protection MOSFET: 2x TY8205
