The MPQ3410DJ-AEC1-LF-P is a simple and cost effective step down, synchronous switching regulator. This dual output device utilizes a Dual Mode® architecture delivering both constant frequency, fixed frequency operation and pulse frequency modulation control. It can drive up to 2A load current from a buck converter and up to 1.2A from a boost converter.

The MPQ3410DJ-AEC1-LF-P is designed to operate in either an adjustable or fixed frequency mode. In its adjustable frequency mode, the device can be set up to switch at different frequencies, allowing for its use in applications where variable frequency operation is desired. Furthermore, this feature helps reduce system power consumption and EMI radiated from the switching regulators. The MPQ3410DJ-AEC1-LF-P is optimized to deliver current mode switching, providing high efficiency and excellent line and load regulation.

The MPQ3410DJ-AEC1-LF-P also includes a lowvoltage power-on reset, as well as input overvoltage protection and short circuit protection. The device is housed in an industry standard lead free 8 pin SOIC package and is suitable for a wide range of consumer and industrial applications.

Application of the MPQ3410DJ-AEC1-LF-P includes:

• Portable consumer electronics
• Battery powered applications
• Portable communication devices
• Automotive electronics
• Industrial control systems

The working principle of the MPQ3410DJ-AEC1-LF-P is based on the concept of a DC-DC buck-boost converter. In a buck-boost switching regulator, the input voltage is regulated by converting it from a high voltage to a low voltage or vice versa. A buck-boost converter works by first converting the DC voltage to AC voltage and then rectifying the AC voltage back to DC voltage in the output stage.

The MPQ3410DJ-AEC1-LF-P utilizes two MOSFET switches, one in the buck stage and one in the boost stage. During the buck mode, the switch in the buck stage is turned on, causing the input voltage to be reduced. During the boost mode, the switch in the boost stage is turned on, causing the output voltage to be increased. Both the input and output voltages are regulated using the devices internal voltage loop and referencing the current to the output voltage.

The MPQ3410DJ-AEC1-LF-P also features a transient response of less than 10µs, allowing it to quickly and accurately adjust to transient load conditions. The device also allows for soft start, improving system power-up performance and reducing inrush currents.

All in all, the MPQ3410DJ-AEC1-LF-P is an ideal device for a wide range of consumer and industrial applications. It is a cost effective switching regulator that offers high performance and excellent line and load regulation. With its adjustable frequency and low-voltage operation, the MPQ3410DJ-AEC1-LF-P is an ideal choice for power supplies requiring a high degree of accuracy and precision.
