DC DC Converters: JHL0324S15 application field and working principle

DC-DC converters are a type of switchmode power supply units that are responsible for providing the required voltages and currents for communication, electronic and computer systems. One type of DC-DC converter is the JHL0324S15, which is often used in telecommunications applications, since its performance reaches high levels of accuracy and stability.

Application Field

The JHL0324S15 is a high efficiency, 12V DC-DC converter module, housed in an industry-standard, 1" x 2" PCB form factor. It has a power output of 24W with a typical efficiency of 82%. Its application field includes a wide variety of telecom applications such as Optical Transceivers, LAN ONU, OLT and modules, UPS, VoIP phones, ADSL modems and wireless base station. This DC-DC converter is designed to be compliant to safety standards like FCC part 15, EN 55022 Class B, demilitarized zone (DMZ), 4KV surge and EMI.

Working Principle

The JHL0324S15 uses a method known as pulse width modulation (PWM) to convert a direct current (DC) voltage at one level to a DC voltage of a different level. It is configured as a switching dc-dc converter. The circuit works by modulating the width of the square wave pulses that are applied to the input of the converter. When a signal is applied, the regulator will automatically adjust the width of the pulse signal until the output voltage reaches the desired level.

The JHL0324S15 uses a synchronous rectification technique to achieve high efficiency in a wide input range from 4.75 to 14VDC. It also features a full load efficiency of up to 82% and ultra-low power consumption at no-load which is less than 0.3W at 24Vin.

In addition, this DC-DC converter offers protections like input under voltage lockout, overload protection and output over-voltage protection, which are essential for today\'s critical applications. It also has a soft-start function to limit inrush current and protect the AC input system. Furthermore, the JHL0324S15 offers a built-in thermal shutdown function that shuts down the converter when the it overheats.

The JHL0324S15 DC-DC converter is extremely well-suited for many types of communication and computer applications. Its small size, high efficiency and wide input voltage range makes it a perfect fit for telecom, rack mounted applications and other power conversion needs.
