OptiMOS™ 30V Half-bridge

Überblick

Infineon’s optimized solution for wireless power and drives

Infineon's OptiMOS™ technology combined with the PQFN 3x3 package offers an optimized solution for DC-DC applications with space critical requirements. The BSZ0909ND and the new BSZ0910ND fit perfectly in wireless charging or drives (e.g. multicopter, wearables) architectures where designers target to simplify the layout and significantly save space without compromising on efficiency.

  • Asymmetric half-bridge with very low RDS(on) in a small 5x6 mm package outline
  • Source-down low side MOSFET for better PCB cooling
  • Internally connected low-side and high-side (lowest loop inductance)
  • High-side kelvin connection for more efficient driving

  • Compact and simplified layout for DC-DC converter
  • Optimized layout with lowest loop inductivity and best thermal performance
  • High efficiency performance

  • Desktop and server
  • Single-phase and multiphase POL
  • High power density voltage regulator
