Switching Power Supply

High-voltage MOSFETs, synchronous rectifiers, and protection for AC-DC and DC-DC supplies

Magnias's MOSFET portfolio spans the primary-side high-voltage devices (500V to 1000V in TO-220F, TO-252 and TO-247, including 650V and 800V super-junction parts) needed for flyback / LLC topologies, and the secondary-side synchronous rectifiers (60V / 100V / 150V in PDFN5060-8L) used in DC-DC and SR stages. With our Schottky and fast-recovery rectifiers and the TL431BL-B / TL432CL shunt references, Magnias covers the power discretes, protection and housekeeping ICs around your PWM controller. The same parts target fast-charge USB-PD adapters, server / merchant-power supplies, LED drivers, and industrial DIN-rail converters.

Application areas

USB-PD fast charger (20–240 W)

  • 650V HV MOSFET (TO-220F / TO-252), primary switch
  • 60V / 100V SR MOSFET (PDFN5060-8L), secondary side
  • TVS for USB-C VBUS protection
  • VBUS back-to-back MOSFET pair: 60V class for SPR, 100V class and up for EPR
  • Shunt reference for opto feedback (TL431BL-B, TL432CL)

AC-DC server / merchant PSU

  • 650V / 800V N-Ch MOSFET, primary
  • 100V / 150V SR MOSFET, output stage
  • Bridge rectifier / fast-recovery diodes
  • Wide-input LDO (housekeeping)

DC-DC point-of-load

  • Synchronous buck (sub-1V to 6V output)
  • 30V / 60V dual N+N MOSFET, sync rectifier pair
  • Comparator for power-good / sequencing (MVC152)
  • Hot-plug load switch

LED driver / backlight power

  • 60V / 100V N-Channel MOSFET
  • Schottky (boost / freewheel diode)
  • Current-sense comparator
  • ESD on PWM / dimming input

AEC-Q101 (-A) versions exist for many 20V to 100V MOSFETs, for example PMS5R4N10HG-A and PMS1001AL8-A. The 500V to 1000V primary-side MOSFETs have no AEC-Q101 version. Magnias parts are halogen-free and RoHS compliant as standard.
