The AmpRipper 3000 is a next-gen power supply for all your portable/rechargeable projects! With Narrow VDC PowerPath Management and a 3A peak output current, you’ll be able to power your high-current projects and fast charge your battery with a single module. It's a true plug and play battery charger module, compatible with Arduino, Raspberry Pi, teensy, or any other 5V device. The AmpRipper can operate with most 3.7-4.2V lithium-ion or polymer batteries, but to get the most out of this product please use batteries with ≥3000mAh capacity and high discharge capacity (≥2C).
At the core of the AmpRipper is the MP2624 switching-mode battery charger and the MP3423 synchronous boost converter. The MP2624 employs a constant current/constant voltage charge profile, with a fast-charge rate of up to 2.4A. The MP2624’s load-sharing architecture allows for seamless transitions between charge and discharge modes. Power to your project will not be interrupted, even if the battery is disconnected!
The MP3423 synchronous boost converter has 90%+ efficiency at 5V output (up to 3A!). This means you won’t get any nasty voltage dips at high current outputs. Just make sure your battery can handle it! Synchronous operation means you can disconnect the 5V output completely by connecting the (EN)able pin to ground.
The USB-C input is configured as a UFP (upstream facing port) for 5V power input only. The USB-C output is a DFP (downstream facing port) and the USB-A output is a DCP (dedicated charging port), both regulated at 5.25V. This configuration works with most 5V USB-A/C 2.0 and 3.0 devices but may not work with some proprietary devices. Short, thick, & high-quality cables are recommended for high current applications. Both USB-A/C outputs can be connected at the same time, but keep in mind that the total output power is divided. Due to the nature of the design, the input current will always be greater than the output current (up to 2X greater). Therefore, it is essential to use high-quality batteries with max discharge values ≥2X the desired output. Likewise, the pass-through current may be limited to ≤2A with a 3A input. When using as an uninterruptible power supply, keep in mind that output loads >2A will deplete the battery over time. PCB will get hot (up to 120°C) during high-current applications. Allow space between PCB and other components and use a cooling system!
There are 2 LEDs: one for indicating charge status and one for low battery. The charge LED will glow solid orange when charging and will turn off once charging is complete. Power will continue to flow after the charge is complete, so it is normal for the LEDs to turn off during operation. The charge cycle will restart automatically if the battery drops below 4.0V. The charge LED will blink rapidly if the charge is suspended (caused by thermal protection, over-voltage protection, or insufficient input current). The low battery indicator will glow bright red when the battery voltage drops below 3.3V. The system has an absolute minimum battery voltage of 3.0V. Once the battery dips below 3.0V, all operation will be suspended.
