BR200/201
POL Converter Module for 12 V System Intermediate Bus
RTRIM Constant Reference Value for Output Voltage
The output voltage level is set by the value of a resistance con-
nected to the RTRIM pin. The relationship is:
BR200: RTRIM (Ω) = (0.6 × 10,000) / (VOUT (V) – 0.6)
BR201: RTRIM (Ω) = (0.591 × 10,000) / (VOUT (V) – 0.591)
The following table provides representative values for RTRIM to
generate voltages within the specified VOUT ranges:

Reset Conditions
There are two methods for resetting all functions in the
BR200/201 (refer to figure 6):
• Set VIN pin voltage to 0.5V or lower for a minimum of
100 ms, or
• Set the ON/¯O¯¯F¯F pin voltage to 0.27 V or lower for a minimum
of 10 ms
