The BD9540EFV-E2 from ROHM Semiconductor is a high-performance, 2-channel synchronous switching regulator controller designed for applications requiring low output voltages. It utilizes external N-MOSFETs for high efficiency and incorporates Rohm's proprietary H3RegTM technology for ultra-high transient response.
Key electrical specifications include an input voltage range of 7.5V to 20V and a maximum output voltage of 5.5V. The controller features built-in protection mechanisms such as Thermal Shut Down (TSD), Under-Voltage Lock-Out (UVLO), Adjustable Over Current Protection (OCP), Over Voltage Protection (OVP), and Short Circuit Protection (SCP). It also includes a soft start function to minimize inrush current during startup.
This device is available in a 28-VSSOP package with an exposed pad and is designed for surface mounting. Its operating temperature range is -20°C to 100°C (TA). The BD9540EFV-E2 is suitable for applications like LCD-TVs, game consoles, and desktop PCs, particularly for DRAM and graphics chip power supplies.
