Buck-boost-converter
This converter can accommodate wide input voltage swings, such as the 8 to 15 V range typical of a 12 V sealed lead-acid battery. The low battery output indicates when the input voltage drops below 8 V. Pulling the shutdown pin turns off the circuit.
This voltage converter is designed to operate effectively within a specified input voltage range, specifically from 8 V to 15 V, which is commonly encountered in applications involving 12 V sealed lead-acid batteries. It features a low battery output signal that activates when the input voltage falls below 8 V, providing a critical alert for battery management systems to prevent over-discharge and potential damage to the battery.
The shutdown function is implemented through a dedicated pin, which allows for the circuit to be turned off when pulled low. This feature is essential for power-saving applications, enabling the system to conserve energy when the converter is not in use or when the battery voltage is too low to maintain proper operation.
In terms of schematic representation, the converter circuit typically includes several key components: a voltage regulator, input and output capacitors, a feedback network for voltage regulation, and the shutdown control pin. The input capacitor stabilizes the voltage and filters out noise, while the output capacitor ensures a smooth output voltage. The feedback network adjusts the output voltage based on the load conditions and input variations. The shutdown control pin is connected to a switch or microcontroller output, allowing for external control of the converter's operation.
Overall, this converter is suitable for applications requiring reliable voltage regulation from lead-acid batteries while providing essential features for battery monitoring and system control.This converter can accommodate wide inputvoltage swings, such as the 8 to 15-V swing typical of a 12-V sealed lead/acid battery. The low battery output indicates when input voltage drops below 8V. Pulling shutdown turns off the circuit.
