DC DC Converters: JHL0324S12 Application Field and Working Principle

DC-DC converters refer to a power conversion electronics component designed to convert a DC voltage to another DC voltage. The JHL0324S12 model is a type of DC-DC converter specifically belonging to a single/dual output family. This particular model of converter is designed with a wide pin form factor suitable for applications such as communication systems, automotive, industrial control systems, lighting, instrumentation, and medical instrumentation.The JHL0324S12 DC-DC converter is composed of an inductive output stage, a high-frequency transformer, and high-efficiency temperature-compensated regulators. The converter is designed to convert a DC input voltage to an adjustable DC output voltage of 0.75V to 1.5V with a maximum efficiency of 78.7%.The JHL0324S12 operates based on the switching mode power supply (SMPS) topology, also known as the switcher. The working principle of this device consists of four continuous steps which include:1.Input Stage: The input stage converts the DC power supply input voltage to a higher high-frequency AC voltage.2.Floating Switch: The floating switch then turns this input voltage on for a short time, and this is done to charge a power factor correction (PFC) active inductor with the AC line voltage.3.Transformer Isolation Stage: The transformer isolation stage is used to isolate the input stage from the output stage.4.Output Stage: The output stage of the JHL0324S12 is designed with a high-frequency transformer to provide an adjustable output voltage. The JHL0324S12 incorporates a number of protective features to protect the converter from overvoltage, overcurrent, and overtemperature. The input voltage range of this converter is set between 4.5V and 14V. It can also withstand peak voltages of up to 30V for a short period of time. The fail-safe feature on this model is intended to shut off the converter in the case of an overvoltage or overcurrent condition.In addition to providing versatile output voltage and efficiency, the JHL0324S12 also offers a wide range of features which include a power good output, a power loss alert signal, and an output disable pin. The power good output is used to indicate when the output voltage is stable and within the specified limits. The power loss alert signal is provided to alert the system that the input voltage is low or absent. The output disable pin is used to control the output voltage by disabling the converter. The JHL0324S12 is designed to operate between a temperature range of -40 to 85°C, and depending on the necessary components added, it can operate as low as -55°C. It provides up to 1.5A of output current with an adjustable output voltage. It is also offered in surface-mount, through-hole, or single-in-line packages which provide design flexibility for different applications.Overall, the JHL0324S12 DC-DC converter is a high-efficiency, cost-effective power conversion component designed for a variety of applications. It provides adjustable output voltage, reliable protection features, and extended temperature range capabilities. This makes the JHL0324S12 the perfect choice for today’s advanced communication, automotive, industrial control, lighting, instrumentation and medical instrumentation systems.
