BP5234-33A
The BP5232-25A, BP5232-33A, BP5233-33A and BP5234-33A are DC / DC converters that use PWM system and VIF
system. They contain control circuits, switching devices and coils, and operate by only connecting an I/O smoothing
capacitor.
With a high efficiency of power conversion, the modules are available in stand-alone SIP packages with no heat sink
required.
!Applications
Power supplies for copiers, personal computers, facsimiles, industrial equipment, and AV eqipment
