The device also features over-voltage, over current and short circuit protection, as well as a comprehensive fault protection. This article will discuss the application field and working principle of the MPQ8632DGLE-12-P.

Application Field

The MPQ8632DGLE-12-P is suitable for a broad range of applications in the consumer, portable and industrial markets. It is ideal for applications that require a high performance and flexible DC-DC switching regulator solution. The MPQ8632DGLE-12-P is capable of delivering a maximum of 3A of output current in an 8-pin QFN package. It provides a comprehensive set of features including digital compensation, wide range of output voltage (1.8V to 6.5V) and adjustable peak current. Additionally, it provides output voltage selection, soft-start and enable/disable functions.The MPQ8632DGLE-12-P is also suitable for applications with space constraints as it does not require any external components. This helps reduce the total component cost and time to market for applications.

Working Principle

The working principle of the MPQ8632DGLE-12-P is based on the regulation of the voltage between its input and the output. The device is configured by selecting the appropriate output voltage, selecting the output current limit and selecting the frequency.The internal oscillator generates a square wave signal that is used to turn the internal NMOS switch on and off. When the switch is on, the current drawn from the input is transferred to the output voltage rail, and the output voltage is regulated. When the switch is off, the output current is reduced and the output voltage is maintained. The internal current limit circuit ensures that the output current does not exceed the selected current limit. Additionally, the internal PWM logic monitors the output voltage and regulates the on-off cycle of the switch to maintain a constant output voltage.

Conclusion

The MPQ8632DGLE-12-P is a advanced DC-DC switching regulator from the PMIC - Voltage Regulators - DC DC Switching Regulators series. The device is suitable for a broad range of applications in the consumer, portable and industrial markets. The working principle of the MPQ8632DGLE-12-P is based on the regulation of the voltage between its input and the output, through the use of an internal oscillator, NMOS switch and PWM logic. Additionally, the device also provides output voltage selection, soft-start and enable/disable functions.
