DC DC Converters

DC DC converters are a ubiquitous and versatile technology used in many different applications. The IHA0112D09 is a single-phase synchronous switching regulator that provides reliable, efficient DC power from any unregulated input. This article will discuss the application field and working principles of this product.

Application Field

The IHA0112D09 is a highly efficient, simple to use switching regulator designed for industrial and other applications with distributed power needs. This device can provide both 12V and 30V of regulated output from unregulated input voltages ranging from 10 to 24 volts, making it well-suited for endpoint power applications. It is also ideal as a battery charger for 3- to 12-cell Li-ion battery packs.The IHA0112D09 also offers a wide range of additional features. It features output voltage and current protection, integrated EMI and surge protection, and dynamic load transient response. This device also supports many different communication protocols such as Modbus and CAN.

Working Principle

The IHA0112D09 works by converting the input DC voltage to a switched output voltage. This is done via the use of an N-channel MOSFET and a synchronous rectifier circuit. The N-channel MOSFET acts as a switch that is used to convert the incoming DC voltage to a higher voltage or current by turning it on and off at a specific switching frequency. When the switch is turned on, the input voltage is \'stepped up\' from its original level, and when the switch is turned off the voltage is reduced back down to its initial level.The synchronous rectifier circuit, meanwhile, is responsible for maintaining the output voltage. This circuit works by allowing the MOSFET to charge a capacitor to the desired output voltage. When the capacitor is charged it then supplies a constant output voltage to the output of the converter.

Conclusion

The IHA0112D09 is a highly efficient DC to DC converter that can provide a wide range of output voltages from a single DC input voltage. This device is ideal for industrial and distributed power applications, and its features make it well-suited for battery chargers, EMI protection, etc. It also offers a wide range of communication protocols. Understanding the working principle of this device can help you take full advantage of its capabilities.
