The BM2P051 is a PWM type DC/DC converter IC from ROHM Semiconductor, designed for AC/DC applications. It features an integrated 650V MOSFET, allowing for simplified circuit design in low-power electrical converters. The device operates within a power supply voltage range of 8.9V to 26.0V and can handle drain voltages up to 650V. It utilizes current mode control for improved performance in bandwidth and transient response, with a typical switching frequency of 65 kHz. The IC supports burst operation at light loads to enhance efficiency and includes a frequency hopping function to reduce electromagnetic interference (EMI). The BM2P051 also incorporates various protection features, including under-voltage and over-voltage protection, soft start, and over-current protection. Its operating temperature range is from -40¬8C to +105¬8C, making it suitable for a variety of applications, including AC adapters and household appliances.
The PWM type DC/DC converter (BM2PXX1) for AC/DC provide an optimum system for all products that include an electrical outlet.BM2PXX1 supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters.BM2PXX1 built in a HV starter circuit that tolerates 650V, it contributes to low-power consumption. With current detection resistors as external devices, a higher degree of design freedom is achieved. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. The switching frequency is 65 kHz. At light load, the switching frequency is reduced and high efficiency is achieved. A frequency hopping function is also on chip, which contributes to low EMI.We can design easily, because BM2PXX1 includes the switching MOSFET.
You can choose from a variety of power and topology evaluation boards.
