The CHL8325A-02CRT is an integrated differential non-inverting buck module controller, so it is classified as a PMIC-Voltage Regulators-DC DC Switching Controller. This device provides the features of high power, efficiency, over-temperature protection, low standby power consumption, and greater than 12A output current. It is widely used in servers, consumer electronics, power adapters, networking equipment, and industrial equipment.

The primary functions of the CHL8325A-02CRT are to regulate the voltage from a DC input source and convert it to a lower DC voltage for the intended application. The internal main stage controller consists of a differential non-inverting buck controller, an error amplifier, a VDD regulator, an over-voltage protection circuit, and a cycle-by-cycle current sensing circuit. It provides a low voltage/high current/high efficiency operation with a single device, while ensuring proper overvoltage protection. This allows the user to switch different supplies at different voltages and currents.

The CHL8325A-02CRT operates in two modes: continuous conduction mode and discontinuous conduction mode. In continuous conduction mode, the module will constantly provide a steady current to the output stage. This allows for consistent power delivery and is useful for powering applications such as servers. In discontinuous conduction mode, the module will pulse continuously as long as the load requires power, allowing for higher efficiency by only charging the load for as long as needed. This mode is ideal for applications such as consumer electronics, where higher efficiency is desired.

The CHL8325A-02CRT has an over-temperature protection circuit included to ensure the safety of the module in the event of it being exposed to temperatures that are outside of its normal operating range. This protection will automatically shut down the module should it become too hot, protecting it from damage and ensuring that the application remains safe. The module also has a low standby power consumption mode, allowing it to save energy when the application is not in use.

The CHL8325A-02CRT also features a built-in current sensing circuit, allowing the user to monitor output current in real time and adjust the output accordingly. This helps to ensure that the load is not exposed to excessive current and that power delivery is consistent. This is especially useful for applications such as power adapters, where precise current regulation is necessary.

The CHL8325A-02CRT is a powerful, efficient and reliable device, making it an ideal choice for a wide range of applications. Its wide input voltage range, low standby power consumption and over-temperature protection make it a great choice for applications that require reliable power delivery and ultimate safety. The current sensing circuitry enables precise power delivery to the load, further ensuring a reliable operation.
