O Notes: Full electrical, thermal, and efficiency calculations available upon request 1) Length (L) may

vary depending on terminals. Height (H) may vary depending on input / output requirements. 2)

Estimated value for normal conditions. Current rating can be up to 30% higher for through hole

applications.

SURFACE MOUNT DESIGN

Highlights

• Patented (U.S. PAT. 7,129,809) design with superior

thermal management

• High efficiency (low losses), ultra compact, low-profile

• Great co-planarity of terminals due to patented header

offering repeatable height

• Excellent solderability (Pb-free or Pb/Sn Solder)

• Standard sizes / customer configurations

• Quick custom turn-around often without start-up or tool-

ing costs

• Inductors available for design in all packages

Customize beyond these examples!

Rated power 150W-700W/ Frequency range 175-300kHZ

Surface mount (SMD) or through hole (TH)

Topology - Full Bridge, Half Bridge, Full Bridge ZVS,

Push-Pull, Flyback

Current rating max. SMD=20A, TH = +30%

Isolation voltage pri-sec/pri-core 500-5.000VDC

Soft switching, single or multiple outputs

Different switching frequencies, input/output voltages

Primary turns - other number (no fractions)

Secondary Ns1, Ns2 / Ns3 turns 1- 8 (no fractions)

Thermal solutions heat sinks, etc.
