LP3972SQ-A514 is a high-performance, multi-channel power management integrated circuit (PMIC) application field, especially designed with integrated LDO regulators (eleventh generator) optimized for use in low-power embedded systems and battery-powered portable devices. It can provide up to 6 independent regulated output voltages and offers excellent performance over a wide operating temperature range. Additionally, the device offers programmable over-temperature, power supply over-voltage, and under-voltage protection.

LP3972SQ-A514 is designed to meet the critical needs of modern portable or battery powered applications. It can be used to achieve power solutions of up to several watts in combined total. This IC features a wide operating temperature range from -40°C to +85°C and is released for space-constrained applications. It contains an integrated buck converter and eight integrated low-dropout regulators that use low-noise PWM (pulse-width modulation) control. Moreover, the device is available in multiple package sizes and can support designs with up to 4 cell Li-ion batteries and up to 5 high-voltages.

The power management system of LP3972SQ-A514 can be divided into two parts: control system and power conversion system. The control system is composed of a low-power microcontroller unit (MCU), clock generator and other control logic circuits. The MCU, in conjunction with the clock generator, is responsible for managing the system’s operating voltage, maximum and minimum voltages, thermal protection, and over-voltage protection. The power conversion system is composed of the buck converter, eleven LDO regulators, and seventeen low-power MOSFETs. The buck converter is the primary power converter of the entire power system and is responsible for providing a stable and steady output voltage. The eleven LDO regulators are responsible for providing low-voltage local power for peripherals, and the seventeen low-power MOSFETs are used for step-down voltage and current regulation.

The LP3972SQ-A514 is an invaluable tool for portable and battery driven applications. It provides low voltage, high current and high power outputs with low power dissipation. With its highly efficient power conversion, wide operating range and integrated protection features, the LP3972SQ-A514 provides an ideal solution for power management in any mobile device. Whether the application requires a low voltage and high current output, or a more advanced design requiring multiple voltage outputs, the LP3972SQ-A514 is the perfect choice.
