PMIC - Battery Chargers can provide a variety of electronic components with the power they need without the need for additional power supplies. The MP2671DL-LF-P is a good example of such a product.The MP2671DL-LF-P is a complete bipolar linear, synchronous step-down battery charger. It can provide a constant current and voltage output at up to 2A and 16V, respectively. It is designed to reduce the power dissipation, minimize overall solution size and reduce EMI while providing extremely short on-time and fast transient response.The key application field of the MP2671DL-LF-P is in applications where efficient power conversion with low power losses and minimum bill of materials (BoM) is required. It can be found in a variety of Bluetooth low energy (BLE) and industrial internet of things (IIoT) systems, as well as in telecommunication, healthcare and automotive applications.When it comes to working principle, the MP2671DL-LF-P consists of an integrated synchronous rectifier stage, an output voltage feedback circuit, an input voltage feedback circuit, multiple protection circuitry and a shutdown control pin. As the supply voltage is connected to the charger, the rectifier stage will attempt to keep the current flowing and the output voltage stable.The input voltage feedback circuit is important for system protection. It monitors the input voltage to make sure the charger does not exceed the maximum voltage rating or enter into an over-voltage condition. The output voltage feedback circuit measures the output voltage and compares it against a target voltage. For example, if the required output voltage is 9V, the feedback circuit will boost or reduce the current to maintain the 9V output.When it comes to safety, the MP2671DL-LF-P has multiple built-in protective functions including over-voltage protection, under-voltage protection, short-circuit protection, over-temperature protection and reverse battery protection. This ensures maximum system protection and superior reliability.In summary, the MP2671DL-LF-P is a charge pump based linear, synchronous step-down battery charger. Its application can be found in many systems requiring efficient power conversion including Ble and IIoT systems as well as telecommunication, healthcare and automotive applications. With multiple protections and adjustable feedback circuit, the MP2671DL-LF-P can ensure optimal performance of the connected system.
