5A and 10A Power Modules

National Semiconductor adds 5A & 10A power modules with low EMI to the SIMPLE SWITCHER® family

National Semiconductor LMZ Low EMI, 5A & 10A Power Modules National Semiconductor's SIMPLE SWITCHER® power modules are the first to drive up to 10A of output current and comply with the CISPR 22 (Class B) radiated and conducted electromagnetic interference (EMI) standard in industrial and communications infrastructure applications. National’s modules include new features for current sharing and frequency synchronization. For high-current intermediate rail and FPGA applications, multiple SIMPLE SWITCHER modules can be placed in parallel to achieve output currents from up to 60A. A synchronization pin enables the modules to operate at the same frequency, controlling switching noise in sensitive systems. They are pin-to-pin compatible with other family members.

  Features   Applications

  • Fast transient response for powering FPGAs and ASICs (LMZ22005 & LMZ23605)
  • Point of load conversions from 12V input rail (LMZ12010 & LMZ22005)
  • Point of load conversions from 12V and 24V input rail (LMZ23605)
  • Time critical projects
  • Space constrained / high thermal requirement applications
  • Negative output voltage applications
