AP2132BMP-2.5TRG1 Application Field and Working Principle

The AP2132BMP-2.5TRG1 is a two-phase linear voltage regulator specially designed for low voltage power supplies. It integrates a dual-phase boost linear regulator, a positive linear regulator and a negative linear regulator to provide several output voltage levels that can be adjusted. All connections are isolated from the output.The AP2132BMP-2.5TRG1 is designed to meet the specific needs of applications that require a wide range of input and output voltages. It features high efficiency and low noise operation, allowing it to work in a wide range of input voltage conditions. It is suitable for industrial, commercial and automotive applications, where low voltage is necessary.

Structure and Working Principle

The AP2132BMP-2.5TRG1 consists of two main components, namely the two-phase boost linear regulator and the negative linear regulator. The first part, the two-phase boost linear regulator, works like a traditional boost regulator with a master section and slave section. It has two high side MOSFETs and two low side MOSFETs in the master section and two low side MOSFETs for the slave section. This helps the device to maintain a constant voltage to the output. The negative linear regulator helps to provide an output voltage which is adjustable. The negative linear regulator consists of a voltage reference and a sensing transistor. The voltage reference acts as a reference to the sensing transistor, the output is then a negative voltage and controlled by the sensing transistor. The device also has current and thermal limit protection. The current limit protection prevents the device from overloading, while the thermal limit protection prevents it from overheating.
