The QSB35024S12 uses a buck synchronous buck-boost topology as its switching mechanism. This means that the converter will first convert the input voltage to an intermediate DC voltage level using an inductor-capacitor (LC) network. This intermediate DC voltage is then boosted or bucked to the desired output voltage level. This converter also features an internal start-up circuit which begins the process by slowly bringing the input voltage to the desired output voltage level.

In addition to the buck synchronous buck-boost topology, the QSB35024S12 also features advanced protection features which ensure safe operation in various potentially hazardous conditions. These include under-voltage lockout (UVLO), over-voltage protection (OVP) and over-temperature protection (OTP). Additionally, the device is equipped with an On/Off enable pin which allows for external control of the converter.

The QSB35024S12 is a high voltage, high efficiency DC-DC converter which is a suitable choice for powering various automotive systems. It offers a wide input voltage range, high efficiency, and advanced protection features. Additionally, it utilizes an LC network, buck synchronous buck-boost topology, and an internal start-up circuit for the efficient conversion of electric energy. Through the use of this device, designers can effectively power their automotive system, without compromising safety.
