PMIC - Voltage Regulators - DC DC Switching Controllers

The SP6133ER1-L/MTR voltage regulator is a high-efficiency and low-cost integrated IC for DC-DC applications. This IC is mainly targeted for applications such as telecommunications, computer, consumer electronics and office automation. With embedded features like Over Voltage Protection, thermal protection, and under voltage protection, the SP6133ER1-L/MTR is highly reliable and well-suited for critical applications. This ic is built to a variety of integrated circuit specifications, some specialized more in line regulation while others provide an exact voltage reference.

Working Principle

The SP6133ER1-L/MTR voltage regulator follows the step-up DC-DC converter principle, also known as boost converter. A boost converter is a voltage regulating device that has a high input voltage and produces a higher output voltage. The boost converter is made up of two bipolar transistors and an inductor.

At the beginning, the transistor is closed and charges the inductor from the input voltage source. After a certain amount of energy is stored in the device, the transistor opens and the energy stored in the inductor is dissipated into the output of the DC-DC converter. The main component of this stage is the current mode control block which is responsible for controlling the switching action of the transistor.

The SP6133ER1-L/MTR has the ability to use pulse width modulation (PWM) and operating at a high switching frequency. This allows the regulator to have a much faster response time and produce a more efficient power conversion and less power dissipation.

Application Field

The SP6133ER1-L/MTR is mainly used in applications such as telecommunications, computers, consumer electronics and office automation. Additionally, this IC can be used in any other application where high efficiency voltage regulation is needed. Since this IC is highly efficient, it is suitable for applications in which the total power dissipation is of low priority.

The SP6133ER1-L/MTR is a widely used component for power applications and is highly reliable even in the most critical applications. This IC is easy to use with its integrated features such as over-voltage protection, thermal protection, and under-voltage protection, making it a preferred choice for power applications.
