DC-DC converters are electrical devices that convert direct current (DC) from one voltage level to another. The JWK2524D15 is a DC-DC converter that allows low-voltage direct current to be stepped-up to a higher voltage for use in power applications.

Overview

The JWK2524D15 is a high performance, low-cost DC-DC converter. It features a wide input range of 4.5 to 20 VDC and provides a 3.3, 5 or 12 VDC output adjustable to no load over the full operating temperature range of -25°C to +85°C. The entire input to output isolation distance is 1000Vdc, which means it is able to handle the majority of demanding digital circuitry. The JWK2524D15 has a power density of over 40 Watts, and can output up to 1.25 Amps in a compact package size of 2.3” x 1.3” x 0.37”.

Applications

The JWK2524D15 can be used in a wide variety of applications where the output voltage must be stepped-up. Common applications include:

• Industrial automation
• Industrial controls
• Portable instrumentation
• LED lighting
• Smart metering
• Surveillance cameras

Working Principle

The JWK2524D15 works on a flyback topology, which is a type of DC-DC converter design. It uses an inductor as an energy storage device and uses MOSFETs to switch between enabling and disabling the inductor.

When the inductor is enabled (switch is closed), energy from the input voltage is stored in the inductor. When the switch is opened, the inductor discharges the energy it has stored, stepping up the voltage to the desired output level. This action is repeated by the switching of the MOSFET, providing an output voltage at the desired level.

Features & Benefits

The JWK2524D15 offers a number of features and benefits including:

• Wide input voltage range (4.5 to 20 VDC)
• High efficiency (up to 86.5%)
• Low ripple and noise (typically 0.4% peak to peak)
• Compact package size (2.3” x 1.3” x 0.37”)
• Low-cost and high reliability
• Full output voltage and current adjustments

These features and benefits mean the JWK2524D15 is an excellent choice for applications requiring high performance, low-cost DC-DC conversion.
