IH0503SH

DC-DC converters, or direct-current-direct current converters, are electronic devices that convert electric energy between low and high-voltage DC systems. IH0503SH is a common model of DC-DC converter which is widely used in multiple power electronics systems and applications.

Applications of IH0503SH

The IH0503SH is a non-isolated DC-DC converter, suitable for high-power applications in the field of industrial, automation, LED lighting, communication, electric vehicle, storage inverter and safety power. It can efficiently convert 9V up to 80V of DC input into a regulated output voltage. The output voltage and current are adjustable through an external shunt resistors connected to the terminals EN and VOUT or by utilizing the PWM input in case of non-linear loads.

Features of IH0503SH

The IH0503SH works within a wide input range from 9V up to 80V with low quiescent current and high efficiency rating of up to 95%. It features a wide temperature operating range from -40℃ to +85℃, high accuracy current limit and short-circuit protection as well as guarded thermal protection. It is also able to store the default settings for fast start-up and ensure the rights output voltage in case of sudden power failure.

Working Principle of IH0503SH

The IH0503SH DC-DC converter works by means of integrating the power transistor and control IC and following the buck or step-down principle. Its working process is simple, where the input current is transferred from the input terminal into an inductor. The charge from the inductor is then stored in the output capacitor to supply the load with the required amount of current. The magnitude of the output voltage is constantly monitored by the IC and adjusted by altering the duty cycle of the PWM signal which controls the frequency of the power switch.

Benefits of IH0503SH

The IH0503SH is a very versatile and reliable DC-DC converter due to its multiple features and low power loss. It is able to provide high efficiency and secure operation even at power failure due to its integrated thermal protection mechanism and output voltage reset. The wide input voltage range allows it to be used in many applications where the voltage might vary. It is also highly suitable for high-power applications because of its cost-effectiveness.

Overall, the IH0503SH DC-DC converter is a highly reliable and cost-effective device which can be used in multiple applications. Its wide voltage range and multiple features make it ideal for industrial, automation, LED lighting, communication, electric vehicle, storage inverter, and safety power. It is also beneficial for high-power applications because of its low power loss and high efficiency.
