ON Semiconductor has integrated its PowerTrench® MOSFET technology to create a rugged integrated solution that delivers industry leading power density and efficiency for DC-DC applications.
What is the benefits of FAN6500X Family PWM Buck Converters
By combining ON Semiconductor’s PowerTrench MOSFET process with industry-leading packaging technology in a PQFN footprint, the FAN65008B/5A/4B PWM buck converters deliver extremely low parasitics in the power path, enabling developers to realize a peak efficiency of 98.5%, with low ringing and better EMI than a solution that uses an external MOSFET.
All three devices support a wide input voltage range from 4.5 V to 65 V, making them applicable to a large range of applications in the Industrial and Consumer sectors, from Base Station Power supplies to Home Automation.
They are also suitable for battery management systems, as well as USB Power Delivery (PD) applications. The integration of two LDOs plus an on-chip Power Path switch gives designers the flexibility to power the controller from the input voltage, the buck converter output or through the PVCC pin using the Power Path.
The high level of integration means manufacturers can use the FAN6500x family to strike the right balance between power density, BoM cost, performance and flexibility.

The History of DC-DC Buck Converters
In the past, most devices have been powered by a mains adaptor that provided a seemingly endless supply of power. Handheld devices such as radios did not integrate complex logic circuits and could handle a wide range of input voltages which meant they could run off several AA batteries. However, as electronics became more advanced and designers started to integrate logic into portable device engineers realized they could no longer get away with making portable toasters.
While linear regulators are still used, they were often the only source of regulation and this typically meant large voltage drops which directly translates to hideous amounts of power loss. One workaround is to use a DC-DC buck convert before the regulator which can take a DC source (such as 12V), and then step it down to 7V. DC-DC buck converters are incredibly efficient (as high as 95%) and are often used to reduce power consumption which can extend the life of portable devices (as well as keeping them cooler).
For those who remember, the ZX Spectrum was also a lap warmer with its 7805 regulator. Image courtesy spdns.DC-DC buck converters have come a long way from their beginnings. They can now be found in very small packages and require very few external components to work.
But DC-DC converters are not without their problems with one of the worse being EMI (electromagnetic interference). EMI is a particular pain in DC-DC buck converters because of the strict regulations on commercial products that require all electronic devices to be both immune to interference and not interfere with other devices. DC-DC converters are usually more than capable of handling external interference, but they are often the source of interference. This is mainly due to the fact that DC-DC converts rely on high-frequency power switching which can very easily emit radio waves. EMI issues can also be exaggerated in high power situations where an external MOSFET is required to handle the large voltages and currents (since the radiating component is now external to the DC-DC IC).
