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
!Features
1) High power conversion efficiency. (BP5233-33A : 93%)
2) Large output current.
3) Low current consumption with no load. (BP5233-33A : 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.

∗A large ripple current flows to the input smoothing capacitor due
to the output load. Be minded to use within the allowable ripple
current of the capacitor.
∗The capacitor with a particularly low impedance is used as the
output smoothing capacitor C2 so as to suppress the output ripple
voltage. Select the capacitor according to the purpose of use in
each case.
