ROHM Semiconductor USA, LLC Voltage Regulators - DC DC Switching Regulators BM2P249TF-E2

The BM2P249TF-E2 is a PWM type DC/DC converter IC designed for non-isolated applications, featuring an integrated switching MOSFET that can tolerate up to 650V. It operates within a power supply voltage range of 10.60V to 26.80V and has a fixed switching frequency of 100 kHz. The device incorporates a built-in high-voltage starter circuit, current detection resistor, and current mode control, which enhances bandwidth and transient response while minimizing power consumption. Key features include a frequency hopping function to reduce electromagnetic interference (EMI), burst operation at light loads, and various protection mechanisms such as under-voltage and over-voltage protection for the VCC pin, as well as an over-current limiter function. The operating temperature range is from -40¬8C to +105¬8C, making it suitable for a variety of applications, including LED lighting, air conditioning, and cleaning devices. The product is packaged in an SOP8 format, measuring 5.00mm x 6.20mm x 1.71mm.
