Description
BD95830MUV is a 2ch switching regulator that can generate low output voltages (0.8V to 5.5V) at the large input voltage range (7.5 to 15V). Space-saving and high efficient switching regulator can be achieved due to built-in 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 power supplies for Digital AV Equipments.

Features
1) 2ch H3RegTM DC/DC converter synchronous controller
2) Built-in N-MOSFET (High side:75mΩ , Low side:50mΩ )
3) Built-in 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)
4) Soft start function to minimize rush current during startup
5) VQFN032V5050 package
6) Built-in 5V power supply for FET drive
7) Integrated bootstrap diode
8) Switching frequency : 400kHz~ 800kHz( depend on input-output condition)

Applications
    LCD-TV, PDP-TV, Set Top Box, Game Consoles, Desktop PCs
