BM2P094F

The BM2PXX4F series, including the BM2P094F, from ROHM Semiconductor are PWM type DC/DC converter ICs designed for AC/DC applications. These ICs provide an optimal system for products with electrical outlets, supporting both isolated and non-isolated devices to simplify the design of low-power electrical converters. The BM2P094F features a built-in 650V starter circuit and a 650V switching MOSFET, contributing to low power consumption. It operates within a power supply voltage range of 8.9V to 26.0V and has an operating temperature range of -40°C to +105°C. The device utilizes current mode control for excellent bandwidth and transient response, with a typical oscillation frequency of 65kHz. At light loads, the switching frequency is reduced to achieve high efficiency, and a frequency hopping function is included to lower EMI.

The BM2P094F is housed in a SOP8 package with dimensions of 5.00mm x 6.20mm x 1.71mm. Key features include per-cycle overcurrent protection, soft start, and various protection functions such as VCC pin under/overvoltage protection and SOURCE pin open/short protection. The typical ON resistance of the internal MOSFET is 8.5 Ω. This IC is suitable for applications like AC adapters and household appliances such as vacuum cleaners, humidifiers, air cleaners, air conditioners, IH cooking heaters, and rice cookers.
