• Overcurrent protection function
Package: Module
Description
The BR200 and BR201 are thin type POL converter modules
with an industry standard exterior shape and footprint,
responsive to very high speed loads and compatible with
ceramic capacitors.
They can be used as design-free POL converters for a 12 V
system intermediate bus. They 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 BR200/201
electrical 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 BR200/201.
Ripple Voltage Measuring Method
Figure 8 provides the test measurement circuit used for establish-
ing voltage ripple.
