Description
The BR206 is a thin type POL converter modules with an industry
standard exterior shape and footprint, responsive to very high
speed loads and compatible with ceramic capacitors.
It can be used as design-free POL converters for a 5 V system
intermediate bus. It can be configured easily, reducing overall
design time, and allowing reuse of designs.
Miniaturization was achieved by high frequency switching
technology, allowing saving space on the application PCB.
Soldering capability has been significantly improved by
adoption of end face through holes.

Application Information
Test Measuring Circuit
The test measuring circuit used for establishing the BR206 elec-
trical characteristics is is shown in figure 7.
The decoupling capacitors, CIN and COUT , should be ceramic
capacitors, placed near the I/O terminals of the BR206.
Ripple Voltage Measuring Method
Figure 8 provides the test measurement circuit used for establish-
ing voltage ripple.
