There are many 24-volt and 12-volt rails available in industrial, medical, and measurement applications that need a bulk converter to step the voltage down to a lower voltage and deliver up to 15 amps. These applications often require a very efficient and compact solution. Hi, I'm Davood Yazdani, Product Marketing Manager at Intersil, a Renesas Company. Here, I would like to introduce the industry first, encapsulated 42 volts, 15 amp power module, the ISL8215M.

A classic point of flawed implementation requires a careful selection of the appropriate controller, gate drivers, power MOSFETs, inductor, as well as resistors and capacitors. By integrating most of these discrete components in a single 13 millimeter by 19-millimeter package, the ISL8215 provides two immediate benefits: a more compact design, leading to increased power density, and a simplified design, leading to shorter development time.

The highly efficient ISL8215M operates from a wide input voltage, up to 42 volts, covering 12 volts and 24 volts, industrial standard voltage rates, and delivers up to 15 amps of continuous current. The ISL8215M perfectly suited to generate the common intermediate bus rails such as 5 volts, 3.3 volts, and 12 volts voltage rails. The typical application circuits shown here illustrates how simple and easy it is to implement your power supply using the ISL8215M.

The ISL8215M is designed to reduce the components count by providing configuration pins that can be directly tied to VCC or ground. A simple resistor or capacitor further expands the options. For instance, adjust the switching frequency, select the light load mode, set the soft‐start ramp time, and program the overcurrent threshold. As shown here, the ISL8215M provides one of the most efficient solutions in the marketplace today, capable of achieving a peak efficiency of 96.5%.

One of the key differences here of the ISL8215M, and in fact, for Intersil power modules, is our differentiated packaging technology which allows for highly efficient heat transfer to the PCB. The thermal tests, as shown here, show that the ISL8215M can safely deliver 10 amps of continuous current at 85° Celsius ambient temperature, and a 24 volt to 3.3-volts conversion, thereby delivering 33 watts of power at 85° ambient with no airflow or dedicated heat sink.

To support our customers, online resources such as design files and iSim are available for the ISL8215M. For more information, please visit us at intersil.com/powermodules.
