DC-DC converters are widely used in the electronics industry. The IE1209D is a new type of DC-DC converter which offers high efficiency and excellent performance for all ranges of operating power. It has been designed for use in a variety of applications, providing reliable and robust operation under varied conditions.

The IE1209D is a highly integrated single phase synchronous buck DC-DC converter, featuring a wide input voltage range up to 100V. It’s maximum output current is 12A, with a peak current rating of 25A. It offers a high efficiency of up to 97.5%, at an input voltage of 55V.

At the heart of the IE1209D is a pulse width modulator control circuit. This is used to regulate the output voltage of the device, according to a reference voltage. Input voltage is fed through a current limiting component, before the controller then feeds the current to the active components, in a series configuration.

The main switching devices consist of two MOSFETs, with a high frequency transformer used to step up and step down the voltages to the desired output levels. The feedback voltages are fed through the sensing resistor, which determines the output voltage level. The output is then rectified, filtered and regulated to provide a stable DC voltage.

The IE1209D also features several safety features, designed to protect against any surge or overloads. A current limit feature prevents the output current rising too high, and a voltage limit feature will cut off the output if the output voltage rises too high.

The IE1209D is ideal for use in low power applications such as medical imaging, communication systems, consumer electronics and battery-powered devices. Its wide input voltage range, high efficiency and reliable operation make it an ideal choice for a variety of applications.
