Beschreibung

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.

Eigenschaften

  • 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

Typische Anwendungen

  • LCD TVs/ Set Top Boxes (STB)/ DVD/Blu-ray players/recorders/ Amusement
  • Broadband Network and Communication Interface
