BM2P0161 Reference Board
BM2P0161-EVK-003
ROHM BM2P0161-EVK-003 is from wide input voltage (90Vac〜264Vac) to output 12V 2A max. Constant Voltage Reference board. It used to
PWM method DC/DC Converter IC BM2P0161.
BM2P0161 is including 650V High voltage power MOSFET and starter. The starter realize low Stand-by Power. Output voltage control method is
used current mode regulation, therefore it can used cycle by cycle current limit. Quick response in dynamic load changing is achieved.
Switching frequency is fixed 65 kHz. Light load situation has frequency decrease function for higher efficiency. Switching frequency jitter function
enables lower EMI operation. Various functions are included for safety, Soft start, Frequency Burst Mode, VCC OVP, Output OLP and thermal shut
down.
