| BD95821MUV 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 BD95821MUV is designed for power supplies for Digital AV Equipment. |

Product Overview BD9611MUV |
| The BD9611MUV is a high-resistance, wide voltage input (10V to 56V), synchronous step-down switching regulator. BD9611MUV offers design flexibility through user-programmable functions such as soft-start, operating frequency, high-side current limit, and loop compensation. BD9611MUV uses voltage pulse width modulation, and drives 2 external N-channel FETs. The Under-Voltage Locked Output (EXUVLO) protection connected to its CTL terminal has high accuracy reference voltage. Its threshold voltage can be adjusted by the resistance ratio between VCC and GND as seen by pin CTL. BD9611MUV is safe for pre-biased outputs. It does not turn on the synchronous rectifier until the internal high-side FET has already started switching. |
|
• High Resistance and Wide Range Voltage Input :
VCC=10V to 56V
• Regulated Voltage Output to Drive External FET
gate: REG10=10V
• Internal Reference Voltage Accuracy: 0.8V±1.0%
• Safe for Pre-biased Outputs
• Adjustable Operating Frequency and Soft-start
• Master/Slave Synchronization
• Over Current Protection (OCP)
• Under Voltage Locked Output (UVLO, EXUVLO)
• Thermal Shut-down (TSD) |

Product Overview BD9615MUV-LB |
| This is the product guarantees long time support in Industrial market. BD9615MUV-LB is a low side MOSFET controller with high withstand voltage (60V). It is suitable for circuits requiring low side FET such as boost and flyback, and it can be used in various applications. An external resistor can adjust the switching frequency from 100kHz to 2500kHz. It reduces the total mounting area because It can operate at extremely high switching frequency. In addition, it has an external clock synchronization function to perform noise management. BD9615MUV-LB has Thermal Shutdown (TSD), Over Voltage Protection (OVP), and Over Current Protection (OCP) to prevent damage caused by various abnormal modes. |
