PMIC - Voltage Regulators - DC DC Switching Regulators

The LT8630EFE#PBF is a high-performance synchronous PWM buck regulator with a fully integrated high-side and low-side N-MOSFETs. It is mainly used in the field of voltage regulation and power conversion, and can be widely used in IoT applications, consumer products, industrial equipment and automotive systems.

Working Principle

The LT8630EFE#PBF uses an internal high-side/low-side N-MOSFETs to control the switching of the voltage regulation and power conversion, and then regulates the output voltage. It receives an input voltage, which is initially regulated by an internal error amplifier and feedback loop. The voltage regulation is applied through a feedback loop that contains an internal error amplifier, sensing circuitry and external components such as resistors and capacitors. The output voltage will be regulated with the feedback received from the sense circuit.

The LT8630EFE#PBF employs a voltage mode synchronous PWM control system with an adjustable switching frequency from 200 kHz to 2 MHz. This control system accurately regulates the output voltage with cycle-by-cycle current limiting. The current limit can be adjusted through an external resistor.

In addition, the LT8630EFE#PBF contains other protection circuitry, such as over current protection, over voltage protection, thermal shutdown protection and UVLO. The device also contains an internal voltage regulator that supplies all internal circuitry.
