DC-DC converters are electronic circuits or devices that are used to convert direct current (DC) from one voltage to another voltage. The LMZ12001EXTTZE/NOPB converter is an integrated switching converter designed for use in applications that require high efficiency, low noise, excellent thermal performance, and a wide input voltage range. This article will provide an overview of the LMZ12001EXTTZE/NOPB converter and its application field and working principle.

Application Field

The LMZ12001EXTTZE/NOPB is ideally suited for a wide range of applications, including buck and boost applications. The LMZ12001EXTTZE/NOPB converter can be used to convert a 3.6V input voltage to a 9V output voltage, or from a 12V input to a 19V output. It supports wide input voltage range, up to 24V, and adjustable output voltage by a single resistor. The LMZ12001EXTTZE/NOPB converter is a 1A DC/DC converter with built-in high efficiency (up to 96%), high frequency operation (up to 2MHz), and low noise. Its high efficiency, wide input voltage range, and low noise makes it a good choice for powering mobile phones, laptops, tablets, and other portable devices. The LMZ12001EXTTZE/NOPB converter is also suitable for industrial and automotive applications.

Working Principle

The LMZ12001EXTTZE/NOPB converter works on a DC to DC conversion principle. It utilizes an inductor to store energy during a switching event, and when the current through the inductor is reversed, the stored energy is dissipated as heat. The inductor converts the current into a voltage, which is then rectified and filtered into the desired output voltage. The LMZ12001EXTTZE/NOPB converter uses synchronous rectification for high efficiency operation. During the switching event, the input voltage is switched on and off at the same frequency as the output voltage. This allows the converter to achieve high efficiency operation, as well as low noise operation.

Control System

The LMZ12001EXTTZE/NOPB converter features a proprietary control system that ensures accurate, consistent, and reliable operation. The control system is implemented using a digital timer-based pulse-width modulation (PWM) technique. The control system features a user-programmable frequency control and adjustable minimum duty cycle. This allows the user to adjust the converter\'s operating frequency and output voltage range. The control system includes an adaptive charging system that allows the LMZ12001EXTTZE/NOPB converter to be used with Lithium-ion batteries, making it suitable for use in portable applications.

Safety Features

The LMZ12001EXTTZE/NOPB converter features overvoltage protection (OVP), overcurrent protection (OCP), and short circuit protection (SCP) to ensure safe operation. The OCP, SCP, and OVP features help protect the device from over-current and short circuit conditions, ensuring reliable operations and long-term device stability. Additionally, the LMZ12001EXTTZE/NOPB converter features an adjustable soft-start feature that helps reduce inrush current during startup and helps prevent electrical noise generated by the converter.

Conclusion

The LMZ12001EXTTZE/NOPB converter is an integrated switching converter designed for applications that require high efficiency, low noise, and adjustable output voltage. It is ideally suited for a wide range of applications, including buck and boost applications. The LMZ12001EXTTZE/NOPB converter features a proprietary control system that ensures accurate, consistent, and reliable operation. It also features overvoltage protection (OVP), overcurrent protection (OCP), and short circuit protection (SCP) for safe operation. The LMZ12001EXTTZE/NOPB converter is a great choice for powering mobile phones, laptops, tablets, and other portable devices.
