Introduction

The BU30JA2MNVX-CTL is a 3-phase step-down voltage regulator specifically designed to be used in multiple applications. This device is a directional controller that supports a range of input voltages up to 25V, and provides a regulated output voltage of 3.3V with a maximum current rating of 10A. The output voltage can also be adjusted by an internal or external bias voltage.

This device utilizes three separate n-channel power MOSFETs for each phase, allowing for independent control and adjustable currents in each of the three phases. The constant current control and low-ripple inductor current limit feature of the BU30JA2MNVX-CTL helps maintain an exact voltage for all three phases, resulting in improved stability, efficiency and reduced heating. Additionally, the inter-phase protection circuitry of this device helps protect it from thermal and electrical damage.

Additionally, it is also suitable for consumer applications, including consumer electronics, the Internet of Things, smart home devices, and more.

Working Principle

The BU30JA2MNVX-CTL is a linear voltage regulator that works by using three power MOSFETs to sense and control the output voltage. When the output voltage requirement is satisfied, the input voltage is switched and the output voltage is maintained at the preset level.

The device operates in a constant-current configuration, allowing it to maintain a steady output voltage without excessive current fluctuations. In addition, the device also has constant on-time and off-time set points, which are configurable through an internal or external external bias voltage. This allows the user to customize the balance of power efficiency and output voltage regulation.

The BU30JA2MNVX-CTL has an integrated inter-phase protection circuitry which reduces loss and helps safeguard the device from thermal and electrical damage. Additionally, a low-ripple inductor current limit feature helps ensure uniform current delivery and reduce heating.
