BD9536FV

High Performance Regulators for PCs 2ch Switching Regulator for Desktop PC BD9536FV No.10030EAT35 ●Description BD9536FV is a 2ch switching regulator controller that can generate low output voltages (0.7V to 5.5V) from a wide input voltage range (7.5V to 15V). High efficiency for the switching regulator can be achieved due to its internal 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, variable frequency, and short circuit protection with timer latch functions. This switching regulator is specially designed for DRAM and power supplies for graphics chips. ●Features 1) 2ch H3RegTM DC/DC converter controller 2) Thermal Shut down (TSD), Under-Voltage Lock-Out (UVLO), Adjustable Over Current Protection (OCP): detected FET Ron, Over Voltage Protection (OVP), Short Circuit Protection (SCP) built-in 3) Soft start function to minimize rush current during startup 4) Adjustable switching frequency (f = 200 kHz – 600 kHz) 5) SSOP-B28 Package 6) Built-in 5V power supply for FET driver 7) Integrated bootstrap diode ●Applications LCD, Game Consoles, Desktop PCs www.rohm.com © 2010 ROHM Co., Ltd.
