BD9E102FJ-GE2

The BD9E102FJ-GE2 from ROHM is a 1A, integrated MOSFET single synchronous buck DC/DC converter in 8 pin SOIC package. It is a synchronous buck switching regulator with low on-resistance built-in power MOSFETs. High efficiency at light load with a SLLM (Simple Light Load Mode). It is most suitable for use in the equipment to reduce the standby power is required. It is a current mode control DC/DC converter and features high-speed transient response. Phase compensation can also be set easily. It features over-current protection, short circuit protection, thermal shutdown protection and undervoltage lockout protection. It is used in consumer applications such as home appliance, telecommunication devices, secondary power supply and adapter equipments.

Avvertenze

Operating IC over absolute maximum ratings may damage IC. Damage can be short circuit between pins or an open circuit between pins and internal circuitry. Consider circuit protection measures.
