TL100024

AC DC Converters

The TL100024 is a high performance switching DC/DC converter that is typically applied in communication, measuring, controlling and protection equipment. It is designed with logic-controlled CMOS technology to operate from a single +7 to +18VDC input. The onboard buck converter provides excellent dynamic performance, high-frequency ripple and low noise. The TL100024 provides an output voltage that ranges from 0V to +5V with a minimum load of 1.5A. The output can be adjusted by an external resistor divider connected to the adjustment pin.

Key Features of the TL100024

• Wide Input Voltage Range - +7V to +18V
• High Efficiency - up to 92%
• High-Frequency Ripple Rejection - up to 40 dB
• Low Output Noise - 0.007%.
• Over-Current and Over-Temperature Protection Circuitry.

Working Principle

The TL100024 works on a buck-boost DC/DC converter principle. The switching regulator circuit has a high-current buck converter, an inverter, and a low-power buck converter. The high-current buck converter converts the input voltage of +7 to +18VDC to +5VDC. The inverter inverts the +5VDC to -5VDC for the low-power buck converter, which then inverts the -5VDC to + 5V. The on-board current limit circuitry and over-temperature sensing circuitry protect the TL100024 from excessive current or temperature.

Applications

The TL100024 is often used in communications and instrumentation applications, such as in mobile phones, laptop computers, modems, etc. The low-noise design makes it ideal for signal processing. It is also suitable for harsh environments such as aerospace, automotive and industrial applications. The high-reliability and high-efficiency design makes it suitable for battery-powered systems such as portable medical equipment and industrial sensors. The TL100024 is also used in high-performance DC motors, such as robotics, high-performance computer systems, and renewable energy systems.

Conclusion

The TL100024 is a high performance AC/DC switching converter that provides an adjustable output from 0V to +5V with high-efficiency and low output noise. It is suitable for a wide range of applications including instrumentation, communications, robotics, industrial systems, automotive applications and more. The on-board protection circuitry and high-efficiency design makes it reliable and easy to use for many projects.
