Power management integrated circuits (PMICs) are widely used in numerous applications due to their ability to efficiently manage power within an electronic system. One such PMIC, the CBC915-ACB-TR1, is a specialized power management system that is designed for applications with greater thermal and extreme voltage requirements. This article will discuss the application fields and working principles of the CBC915-ACB-TR1.

The CBC915-ACB-TR1 is designed for systems that require the highest levels of reliability and safety. These types of applications include automotive, medical, industrial, military, and aerospace products. It is specifically designed to provide safe, reliable power and reduce system power losses during operation.

The CBC915-ACB-TR1 is designed to provide consistent power at high temperatures, up to 150ºC, while also protecting against transient voltage peaks of up to 10kV. The integrated circuit (IC) also offers wide input voltage range of 6V to 36V, high output current capability of up to 3.2A, and low output voltage ripple of less than 4mV. The high power efficiency of up to 95%, low standby current of 12.7µA and reverse-polarity protection make the CBC915-ACB-TR1 a reliable and efficient solution for the most demanding applications.

The CBC915-ACB-TR1 features two distinct circuit topologies: a buck converter and a boost converter. The buck converter converts a higher input voltage to a lower output voltage, while the boost converter does the opposite. Both converters operate independently, but are coordinated by an embedded control system. This enables the IC to achieve a wide input voltage range without sacrificing output power efficiency.

The working principle of the CBC915-ACB-TR1 is based on the combination of the buck and boost converters. The buck converter steps the input voltage down to the required output voltage, while the boost converter boosts the output voltage to compensate for the input voltage changes. The buck converter uses pulse width modulation (PWM) to regulate the voltage, while the boost converter uses a variable frequency technique to keep the output voltage within the desired range.

The CBC915-ACB-TR1 also uses a feedback circuit to regulate its output voltage. This ensures that the output voltage remains within the required range regardless of the input voltage variations. The embedded system also implements the two kinds of overcurrent protection, which are short-circuit protection and over-temperature protection. This provides maximum protection for the system from overcurrent conditions.

The CBC915-ACB-TR1 also features a number of integrated safety features such as an overload protection, programmable soft start, brown-in protection, and thermal shutdown. These features help prevent damage to the system due to excessive voltage or current. The brown-in protection is especially important in automotive and industrial applications, where the system is powered on and off frequently.

In summary, the CBC915-ACB-TR1 power management system is designed to provide the highest levels of reliability and safety in extreme temperature environments. It features the combination of buck and boost converters, with a number of integrated safety features, such as overload protection, programmable soft start, and thermal shutdown. The CBC915-ACB-TR1 is an ideal solution for automotive, medical, military and aerospace applications, as well as industrial applications that require the highest levels of reliability and safety.
