ROHM Semiconductor BM1Q104FJ Quasi-Resonant Control DC-DC Converter
ROHM Semiconductor BM1Q104FJ Quasi-Resonant Control DC-DC Converter provides an optimum solution for applications that include an electrical outlet. The quasi-resonant operation of the BM1Q104FJ enables soft switching and helps keep EMI low. As the MOSFET for switching and current detection resistors are external devices, a high degree of design freedom is achieved. The BM1Q104FJ integrates an HV starter circuit that tolerates high voltage, contributing to the device's low consumption power and high-speed starting capability.
The BM1Q104FJ includes various protection functions, including soft-start, burst mode, over current limiter, overload protection, over-voltage protection, and CS open protection.
The ROHM Semiconductor BM1Q104FJ DC-DC Converter is available in a compact SOP-J8 package with a -40°C to +85°C operating temperature range.
