Multi-chip module PWM buck regulators offer current density and fully integrated mosfets
Three efficient mid-voltage PWM buck converters have been launched by ON Semiconductor.
Supporting an input voltage range of 4.5 to 65 V, an output current of up to 10A and output power of 100W, the company’s FAN6500X family of buck converters combines fixed frequency control scheme with flexible Type III compensation and robust fault protection
By combining ON Semiconductor’s PowerTrench mosfet process with packaging technology in a PQFN footprint, the FAN65008B/5A/4B PWM buck converters deliver low parasitics in the power path, enabling developers to realise a peak efficiency of 98.5 per cent, with low ringing and better EMI than a solution that uses an external MOSFET, says the company. Because all three devices support a wide input voltage range they suit various 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 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 FAN6500x family offers a range of features to protect itself and any downstream circuits from damage. These include adjustable over-current protection, thermal shutdown, over-voltage protection and short-circuit protection.
“With the release of the FAN6500X family of parts ON Semiconductor has produced a series of robust solutions to help customers meet their mid-voltage DC-DC needs with industry leading efficiency, power density, and flexibility,” said Richard Lu, president of mobile, computing and cloud division, ON Semiconductor.
The company also offers supporting evaluation boards:FAN65004B-GEVB, FAN65005A-GEVBand FAN65008B-GEVB. The FAN65004B family comes in a PQFN-35 package and is priced at $2.68 per unit in 3000 unit quantities.
