Description
BD95831MUV is a 1ch synchronous buck converter that can generate output voltage (0.8V to 5.5V) at the input voltage range (7.5V to 15V). Space-saving and high efficient switching regulator can be achieved due to built-in N-MOSFET power transistors. The IC also incorporates H3Reg™ technology, a Rohm proprietary constant ONTIME control mode which facilitates ultra-high transient response against changes in load without external compensation components. Fixed soft start function, power good function, and short circuit / over voltage protection with timer latch functions are incorporated. The BD95831MUV is designed for power supplies for Digital AV Equipment.
Features
- Fast Transient Responses due to H3Reg control
- Over Current Protection (OCP) – Cycle-by-Cycle
- Thermal Shut Down (TSD)
- Under-Voltage Lock-Out (UVLO)
- Short Circuit Protection (SCP)
- Over Voltage Protection (OVP)
- Fixed Soft Start (1msec ; typ)
- Power Good function
Typical applications
- LCD TVs/ Set Top Boxes (STB)/ DVD/Blu-ray players/recorders/ Amusement
- Broadband Network and Communication Interface
