DC-DC converters are electronic devices which convert one DC voltage level from a direct current source to another DC voltage level. The IE1203D DC-DC converter is a newly developed product for automotive applications, which is highly reliable in terms of output power, noise immunity, and energy efficiency. It is a high-performance voltage booster that can be used for various automotive voltage applications.

The IE1203D DC-DC converter is capable of providing regulated output levels up to 50V with a maximum output current of 3A. It uses a high-efficiency 15V input and delivers up to 1.5 kW of continuous output power with a wide input voltage range of 8V to 18V. The device supports a programmable output voltage of 0.6V to 50V and a fast transient response time of less than 0.2µs. Its protection features include over-temperature, input under-voltage, current limits, and reverse-voltage protection.

The operating principle of the IE1203D is based on a buck-boost topology. In this circuit topology, the device attempts to maintain the output voltage regardless of the input voltage level. To fulfill this requirement, it employs a pair of series capacitors, a high-side MOSFET and a low-side MOSFET, connected in parallel to the inductor. A feedback loop is also employed to ensure that the output voltage remains within the desired range. The series capacitors act as a voltage divider reducing the effective output voltage from the input. Despite this, the output remains within a tolerated voltage range under the control of the feedback loop.

The IE1203D is a highly efficient and reliable device that can be used for a variety of automotive voltage applications. It can provide up to 1.5 kW of continuous output power with an input voltage range of 8V to 18V. Its high-efficiency conversion and fast transient response time make it suitable for a wide range of applications. This device is protected against various electrical faults and is thermally protected to prevent damage due to overheating. Its wide input voltage range, programmable output, and programmable current limits make it an ideal solution for automotive voltage requirements.
