The BD9842FV-E2 from ROHM Semiconductor is a versatile IC designed for step-down DC/DC converter applications. It integrates two switching regulator controller circuits utilizing a pulse width modulation system, making it suitable for compact power supply designs.
Key electrical specifications include a wide supply voltage range of 3.6V to 35V and a high switching frequency capability from 100kHz to 1.5MHz. The device incorporates features such as an error amplifier with a precise 1.0V reference voltage (±1%), a 2.5V REG output circuit, and an overcurrent detection circuit. It also supports adjustable soft start and pause periods, along with three operational modes: standby, master, and slave.
Designed for efficiency and flexibility, the BD9842FV-E2 offers independent ON/OFF control for each channel via the DT terminal. Its compact package is optimized for space-constrained applications. The operating temperature range is -40°C to 105°C.
Applications for this controller include LCD and PDP displays, PCs, AV equipment, printers, DVD players, projectors, TVs, fax machines, copy machines, and measuring instruments.
