DC-DC converters are power electronics devices used to adapt a DC input voltage to a different, usually higher, DC output voltage. This can involve a number of functions such as buck-boost, boost, flyback, and forward. The SUTS100512 is a “push-pull” DC-DC converter with high efficiency and a wide input voltage range. The device is highly integrated and utilizes a synchronous rectification technique to provide improved efficiency compared to other traditional DC-DC converter topologies.The SUTS100512 is an optimized DC-DC converter that can be used for a wide range of applications requiring high efficiency and noise immunity. It is specifically designed for small and medium power applications in personal computers, cell phones, and air conditioners. The device can provide an output voltage of 5 V to 12 V. Its peak efficiency is up to 96% and it supports load current up to 5 A.

The SUTS100512 application field and working principle is based on a two-stage topology called a push-pull converter. In this topology, power is transferred from the input to the output via two power stages. The first stage is a high-side buck-boost power stage with synchronous rectification. This stage takes advantage of switching the MOSFETs on and off to convert the input voltage from the battery into an intermediate voltage. This voltage is then transformed by a second stage consisting of an on-time booster with fixed frequency PWM control. This stage provides further conversion of the intermediate voltage to match the desired output voltage.

The push-pull converter has several key advantages over traditional DC-DC converters. These include higher efficiency, smaller solution size, and the ability to operate in a wide input voltage range with low power input. The device also has superior EMI performance due to its symmetry-balanced output structure, as well as an optimized internal leading-edge blanking time to reduce switching surge. The SUTS100512 DC-DC converter is one of the most effective solutions for applications demanding high power efficiency, ease of use, and higher operating frequency. Its two-stage push-pull architecture allows for a high degree of flexibility in terms of input voltage and current, and its integrated synchronous rectification offers improved power efficiency compared to other converters. In addition, its symmetric structure ensures excellent EMI performance, and its temperature protection and soft-start functions add additional protection and safety.
