DC / DC converter
BP5232A25 / BP5232A33 / BP5233A33 / BP5234A33


The BP5232A25, BP5232A33, BP5233A33 and BP5234A33 are DC / DC converters that use PWM system and VFM
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.


zApplications
Power supplies for copiers, personal computers, facsimiles, industrial equipment, and AV equipment.


zFeatures
1) High power conversion efficiency. (BP5233A33 : 93%)
2) Large output current.
3) Low current consumption with no load. (BP5233A33 : 200µA Typ.)
4) High conversion efficiency. (85% at output current of 100mA)
5) Applicable to various purposes by fine-adjusting output voltage with external circuits.
6) Built-in ON / OFF switch.
7) Heat sink unnecessary.
