DC-DC converters are important components used in various power supplies and electronic devices. The ZUS34812 is a buck synchronous, low-noise, low-distortion, switching DC-DC converter from ON Semiconductor. It can efficiently convert a high input voltage into a regulated low voltage output. The ZUS34812 integrates a buck switching controller and two power MOSFETs to simplify power supply design, reduce rends, and facilitate cost savings.

The ZUS34812 has a wide 4.5 V to 28 V input voltage range and a 1.2 V to 24 V adjustable output voltage range. It also features low-ripple noise of only 10mV RMS for better audio and video performance. With a wide input range, high efficiency (up to 95%), and up to 4.5A output current, the ZUS34812 is suitable for use in various applications such as Advanced Geolocation Technology (AGT) Systems, IGBT/Power Electronics Applications, Automotive systems, and many others.

The ZUS34812 operates from a single pin PWM signal, hence making it highly flexible in its operation and allowing for closed loop control. Its high-speed operation and minimal external components make it ideal for Compact Low Profile (CLP) embedded applications, saving significant board space and simplifying power supply design.

The ZUS34812 features both the self-protection mode and the bypass mode. In the self-protection mode, the maximum output current limit and the output over-voltage protection are provided. In the bypass mode, the output voltage is equal to the input voltage, making the output voltage fluctuation less than 2%. This makes the ZUS34812 ideal for use in high load, high efficiency application.

The ZUS34812 has a wide input voltage range and adjustable output voltage range, high power conversion efficiency, and low-noise output. Its self-protection mode with over-current and over-voltage protection, bypass mode, and flexible single-pin PWM control make it ideal for use in a wide range of DC-DC converter applications including AGT systems, IGBT applications, automotive systems and many others.
