Package: Module
Description
The BR202 and BR203 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.

BR202/203
POL Converter Module for 12 V System Intermediate Bus
Functional Description
Power Good ( PG) Operation
When output voltage, VOUT , is within the Power Good detection
range, the PG pin is disconnected internally by the MOSFET
switch. The signal at the Power Good node is pulled up to 5 V. If
VOUT falls out of the Power Good detection range, the MOSFET
switch connects PG to GND, and the signal at the Power Good
node is pulled low. The PG peripheral circuit is shown in figure 3.
Output Sensing ( VS+) and Compensation
Reduction in output voltage can be compensated by connecting
the output sense terminal, VS+ , to the load. When using LC filter,
the proper connection is shown in panel A of figure 2. Note: Do
not connect the output sense terminal to the output of the LC
filter. It may not operate normally.
CAUTION: When the output sense terminal is not used, it must
be connected directly to the VOUT output terminal. This is shown
in panel B of figure 4.
External On/Off Output Control (ON/¯O¯¯F¯¯F¯)
Operation of the output of the product can be turned on and off by
using the On/Off function, irrespective of input voltage connec-
tion.
This is enabled by connection of the ON/¯O¯¯F¯F pin (pin 1) (refer to
panel A of figure 5):

Load
• When the ON/¯O¯¯F¯F pin is open, the output voltage is on
• When the ON/¯O¯¯F¯F pin is connected to GND, the output voltage
is off
Multiple BR202 and BR203 devices can be controlled by the
same switch, by connecting the devices in parallel across the
switch (refer to panel B of figure 5).

CAUTION:
• The ON/¯O¯¯F¯F pin is pulled up to VIN via a resistor and is con-
nected to GND via a resistor inside the BR202/203 converters.
• The ON/¯O¯¯F¯F pin voltage is set to around 40% of VIN. Do not
feed voltage higher than 7 V to the pin from outside the
BR202/BR203 converters.
• When the ON/¯O¯¯F¯F pin voltage is higher than 5.5 V, connect a
1 kΩ resistor to the ON/¯O¯¯F¯F pin in series.
