CHL8112A-05CRT is an integrated multiple-output step-down power supply that is designed to provide a high efficiency and cost-effective solution for dual-core SoC applications.It consists of an integrated controller, power FETs, inductors, and all the necessary passive components. The device provides a wide input range and each of the integrated outputs can be adjusted either by an external voltage divider or through the I2C interface. The device supports output voltage measurements and load current measurements by using the I2C interface.

The application field of the CHL8112A-05CRT could be any equipment that requires an efficient and reliable power supply to maintain its operation. Examples of these systems include DTVs, radios, computers, telecommunication systems, and many other consumer-type products. In these systems, the CHL8112A-05CRT can provide a highly efficient power supply solution, replacing the need for discrete components, and thus reducing board area, cost and complexity.

The CHL8112A-05CRT\'s working principle is based on the buck-converter operating concept. It takes an input voltage and reduces it to a predetermined level that is required by system components. It consists of three main stages: a power stage, a controller and an analog feedback loop.

The power stage is composed of a MOSFET and an inductor, which are connected in series. The inductor acts as a buffer between the input voltage and the load. When the MOSFET is in its ON state, the input voltage charges the inductor, and when it is turned OFF, the charge stored in the inductor releases and provides the load voltage.

The controller is a critical element of the power supply system, which controls the current and voltage levels and provides a feedback circuit for components such as the MOSFET and inductor. The CHL8112A-05CRT uses a fixed-frequency current-mode control to ensure accurate and stable output regulation.

The analog feedback loop is responsible for monitoring the output voltage and regulating it. The CHL8112A-05CRT includes an integrated high-speed voltage feedback error amplifier, which allows for reliable and precise output voltage regulation. It also features an on-chip power-sharing controller that optimally allocates the power delivery of both buck converters to meet their respective load demands.

In conclusion, the CHL8112A-05CRT is an integrated multiple-output step-down power supply designed to offer an efficient and cost-effective solution for dual-core SoC applications. Its working principle is based on the buck-converter operating concept that takes an input voltage and reduces it to a predetermined level. The device includes an integrated controller, power FETs, inductors, and all the necessary passive components. It features a fixed-frequency current-mode control and an integrated high-speed voltage feedback error amplifier to ensure accurate and stable output regulation.
