Introduction to UCC24610DR

The UCC24610DR is a Simple Switcher power supply controller from TI. It is customized specifically for low power applications and offers a variety of features that make it an ideal choice for applications such as network power supplies, chargers, point-of-load regulators, and more. The UCC24610DR is part of the UCC246xx family of devices, which offer excellent performance, high efficiency and minimal external components requirements.

Power Supply Controller/Monitor

The UCC24610DR is a power supply controller specifically designed to simplify the implementation of low-power applications. It is a Simple Switcher, which means that it is a single-channel device that requires a minimum number of external components to construct a power supply solution. The device has an internal voltage reference, voltage sense amplifier, current sense amplifier, and over-current protection, making it ideal for applications with ultra-low power requirements. The UCC24610DR also features a precise 4V output voltage accuracy and a wide input voltage range (4.5V- 30V). This makes it suitable for applications such as notebook computers, cell phones, personal digital assistants (PDAs), or any other low-power applications. Additionally, its internal temperature compensation offers enhanced accuracy across a temperature range of −40°C to +125°C. The UCC24610DR is capable of providing up to 2.6A of output current, with a high efficiency rating of up to 95% at 7V out. The device contains protection features such as an over-voltage protection and an over-current protection that protect the application from fault conditions.

Working Principle and Application Field

The working principle behind the UCC24610DR is simple. It utilizes a simplified two-phase design, with two switches, one for positive output, and one for negative output. The regulation of the output voltage and current is achieved by sensing the application load current and adjusting the duty cycle of the output switches in order to maintain the proper output voltage. A wide range of applications are possible with the UCC24610DR. It is suitable for applications such as DC/DC converters, battery chargers, gate driver and LED driver solutions, network power solutions, and even power supplies for FPGAs. It can also be used in commercial and industrial applications, such as solar applications and motor control systems.

Conclusion

The UCC24610DR is an excellent power supply controller, offering superior performance and multiple features ideal for low-power applications. Its 4V output voltage accuracy, wide input voltage range, and up to 95% efficiency makes it suitable for a variety of applications. Additionally, its low external component requirements provides greater design flexibility, while the internal over-voltage and over-current protection provides an added layer of protection against fault conditions. All of these features make the UCC24610DR an ideal choice for any low-power application.
