This chip can be utilized as a single-channel or dual-channel power switch. It can be used in power supply design, power conversion and voltage control.

Features

TPS2223 ADB provides advanced features such as:

• Adjustable Current Limit,
• Integrated Programmable Thermal Warning,
• External Programmable Overvoltage Protection,
• High Efficiency,
• Low Quiescent Current and
• Programmable Off-Time Ratio.

Application Field

The TPS2223ADB IC is suitable for a wide range of applications including hand-held devices and laptop computers. It is compatible with devices such as digital cameras, camcorders, audio players, and portable media players. Its features make it an excellent choice for converters, modems, and battery-powered appliances.

It is also used in systems requiring high efficiency, high power density, and high performance. The TPS2223ADB is a highly reliable, low power device designed for power conversion in industrial, automotive, and consumer applications.

Working Principle

The TPS2223ADB works with a pulse-width modulation (PWM) control scheme. It is a current dithering mechanism that is used to reduce ripple in the output voltage. The PWM control scheme also provides frequency shifting (for transient blackouts) and dynamic voltage scaling (for continuous current regulation).

The chip has two identical output channels. The two channels can be independently adjusted using the internal programmable current limit to set the maximum current allowed through each channel. This allows for independent, simultaneous control of each channel\'s output voltage.

The TPS2223ADB can also be used for sequencing multiple supplies for increased safety and reliability. The sequencing system uses a timer controlled by an external resistor and an external capacitor to sequence voltage outputs from a single, low cost, and low power device.

The TPS2223ADB is designed to provide an efficient, low-cost solution for battery-powered devices such as digital cameras, camcorders, audio players, and portable media players. The chip improves efficiency and reduces system power consumption by reducing ripple in the output voltage.
