BP5220X / BP5221X / BP5222X
The BP5220, BP5221, BP5222, BP5220X, BP5221X, and BP5222X are DC / DC converters that use a pulse
width modulation (PWM) system. They contain control circuits, switching devices, rectifiers, 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 9-pin SIP packages with no heat sink required. They can be applied to various purposes
by fine-adjusting the output voltage and switching on and off. With a wide range of input voltage, the modules are
best suited for obtaining a stable local power supply from a main power supply with a large voltage variation.
Applications
Power supplies for copiers, personal computers, facsimiles, AV equipment, measuring instruments, vending
machines, security device, registers, industrial equipment, and maintenance tools
Features
1) Wide range of input voltage.
2) High power conversion efficiency.
3) Built-in output ON / OFF switch.
4) Applicable to various purposes by
fine-adjusting the output voltage.
5) Small number of external components required.
6) Heat sink unnecessary.
7) Compact package.

Circuit operation
(1) The basic application examples are shown in Fig.2.
The externally installed parts are only the input and
output smoothing capacitors.
(2) Switching on and off the output voltage is allowed.
The output can be switched off by making pin 4 to
be open (high impedance). (See Fig.3)

(3) Fine adjustment of the output voltage is allowed.
The fine adjustment of output voltage can be
performed from pin 6 via the resistor by connecting
the output terminal (pin 2) or GND.(See application
example3)

Fig.5
A resistor to secure the rise of output at power on. The resistance to be selected depends on the input voltage.
This is a standard application. Because the control current fluctuates with variations in circuits and components,
set the control current by adding a sufficient margin to the normal current level.
