ROHM Semiconductor USA, LLC Voltage Regulators - DC DC Switching Regulators BD9E102FJ-E2

The BD9E102FJ-E2 is a synchronous buck DC/DC converter designed for efficient voltage regulation. It operates within an input voltage range of 7.0V to 26V and can deliver a maximum output current of 1.0A. The adjustable output voltage can be set between 1.0V and 0.7 times the input voltage. This regulator features integrated MOSFETs with low on-resistance, specifically 250 m,Ѷ for the high-side and 200 m,Ѷ for the low-side, contributing to its high efficiency, particularly at light loads with its Simple Light Load Mode (SLLM). The switching frequency is typically 570 kHz, allowing for fast transient response. Additional protective features include overcurrent protection, short circuit protection, thermal shutdown, and undervoltage lockout. The device is packaged in a compact SOP-J8 format, measuring 4.90 mm x 6.00 mm x 1.65 mm, making it suitable for various consumer applications, secondary power supplies, and telecommunication devices.
