PMIC - Voltage Regulators - DC DC Switching Regulators

The MPQ2451GG-33-P is a monolithic linear voltage regulator integrated circuit used for providing a regulated DC output voltage with excellent line and load regulation characteristics. This product is designed to be used within a wide range of applications such as automotive power systems, telecommunications, industrial and consumer electronics.

The MPQ2451GG-33-P integrates a power MOSFET into a high-efficiency synchronous step-down converter to regulate a DC output voltage down from a nominal input voltage. This allows the device to provide a regulated DC output voltage while consuming very low power. This device also provides an integrated low-side current-sense solution integrated on the device, which enables designers to design a power system with two sensing points for more accurate output voltage regulation.

The MPQ2451GG-33-P employs a synchronous switching frequency of up to 700 kHz, enabling the design of smaller and lighter systems with less external components compared to other DC-DC voltage regulator integrated circuits. Additionally, the device can provide a high efficiency of up to 96%, making it a good choice for applications with tight power source constraints.

The MPQ2451GG-33-P provides constant voltage regulation by maintaining an output voltage between a maximum and minimum operating range given a supply voltage range of 4 to 32V. The user can adjust the output voltage with a voltage divider connected to the BIAS_COMP pin. The output voltage is then regulated using an internal differential amplifier to provide feedback between the reference and error amplifier signals.

The device also provides a current limit feature using an integrated current-sense circuit. The current limit is initiated by the voltage across the internal current-sensing resistor when it exceeds the level set by the external current limit resistor. This feature helps to protect the system from overload conditions. The device also has an integrated thermal protection feature to protect from excessive temperature conditions.

The MPQ2451GG-33-P is a high-efficiency DC-DC voltage regulator that can be used in a wide range of applications requiring an adjustable DC voltage. Its small size and low power consumption make it an ideal choice for applications with tight power source constraints. Its integrated current-sense and thermal protection features help to enhance the reliability and safety of the system.
