Hi-performance Regulator IC Series for PCs  
2ch Switching Regulators  
for Desktop PC  
BD9540EFV  
No.09030EBT07  
Description  
BD9540EFV is a 2ch switching regulator synchronous controller that can generate low output voltages (0.75V to 5.5V). High  
efficiency for the switching regulator can be achieved due to its external N-MOSFET power transistor. The IC also  
incorporates a new technology called H3RegTM, a Rohm proprietary control method which facilitates ultra-high transient  
response against changes in load. For protection and ease of use, the IC also incorporates soft start, and short circuit  
protection with timer latch functions. This switching regulator is designed for DRAM and power supplies for graphics chips.  
Features  
1) 2ch H3RegTM DC/DC converter synchronous controller  
2) Thermal Shut Down (TSD), Under-Voltage Lock-Out (UVLO),  
Adjustable Over Current Protection (OCP) : detected Low side FET Ron, Over Voltage Protection (OVP),  
Short Circuit Protection (SCP) built-in  
3) Soft start function to minimize rush current during startup  
4) HTSSOP-B28 package  
5) Built-in 5V power supply for FET driver  
6) Integrated bootstrap diode  
Applications  
LCD-TV, Game Consoles, Desktop PCs
