IE1212D

DC DC Converters

The IE1212D is a unique DC DC converter, which can be used in a variety of fields due to its highly versatile nature. The IE1212D boasts a wide input voltage range of 4.5 to 20 VDC, an ultra-low quiescent current level of 30mA, and a high power output of up to 3000mA. It is also designed with an EMI filter built-in, allowing for operation in noise sensitive environments.

Application field and working principle

The IE1212D is commonly used in medical, industrial, and consumer electronic applications, due to its high degree of reliability and power output. It is able to provided a single output of 5VDC with a maximum power output of 12W. It can be used to power a variety of devices, such as a laptop or a tablet, and can be used with an external power supply for higher power applications.

The working principle of the IE1212D is based on the Buck Converter topology. A Buck Converter topology is a switching power supply design which takes in an input voltage, regulates it to the desired output voltage, and sends it to the load. The Buck Converter consists of a high-side switch, an inductor, a low-side switch, and a diode to complete the circuit. When the high-side switch is activated, energy is stored in the inductor, and when the low-side switch is activated, the energy will be discharged to the load, providing the desired output voltage. This process is repeated constantly between the high and low switches at a fixed frequency, allowing for a regulated output voltage.

The high-efficiency of the IE1212D is achieved by using synchronous rectification technology and constant on-time topology. The synchronous rectification process eliminates the need for a rectifying diode in the circuit, and allows for more efficient transfer of energy from the input voltage to the output voltage. The constant on-time topology uses a fixed length for the high-side and low-side switching duration, allowing for less power loss as the load and input voltage changes.

The IE1212D also features an integrated EMI filter in order to reduce any unwanted electromagnetic interference to the board\'s electronics. This allows for a higher degree of reliability and compatibility with environmental standards when operating in noisy environments.

The IE1212D is a highly versatile power supply which can be used in a variety of applications. Its reliability, high efficiency, and low quiescent current make it an ideal choice for a wide range of products and applications.
