Product Overview BD8P250MUF-C |
The BD8P250MUF-C is a synchronous rectification buck DC/DC converter with boost control function that utilizes ROHM’s Quick Buck Booster™ technology to achieve improved response even when switching buck-boost operation, reducing the number of output capacitors by half over conventional solutions.
This technology supports a common design for both boost and buck-boost applications. Use the BD8P250MUF-C as a single-chip buck DC/DC converter for cold cranking or other instances where a drop in the output voltage is acceptable during the input voltage drop. Or, if the output voltage must be maintained, it can be utilized in a buck-boost DC/DC configuration by adding a dedicated boost-FET.
Additional features include a spread spectrum function that minimizes EMI, making it possible to easily clear the CISPR 25 Class 5 standard for noise in automotive electrical components and leveraging original Nano Pulse technology reduces no-load current consumption to an unprecedented 8μA at 5V output from a 12V battery. This translates to 73% greater efficiency in buck and buck-boost operation at 0.1mA output load current over competitor products. |

Product Overview BD9015KV-M |
The BD9015KV-M and BD9016KV-M are high performance synchronous rectification switching controllers with wide input range and dual channel output. The synchronous rectification method comes with high efficiency making controller ideal for eco-designs(low power consumption) of numerous electronics. All channels have enable pins, soft start functionality and power good outputs. Startup and shutdown can be controlled independently. An integrated PLL circuit can be synchronized to an external 250kHz to 600kHz clock signal. |

• N channel MOSFET direct drive
• Synchronous rectification for increased efficiency
• Acceptable Low ESR ceramic capacitor at output
• Integrated PLL circuit for external synchronization; 250kHz to 600kHz
• Current mode control
• High side MOSFET current sensing
• Pre-bias functionality
• Independent ON/OFF control for all channels
• At Max Duty the oscillation frequency is slowed down to 1/5, reducing the input/output voltage difference.
• Low voltage and over voltage detection circuit at all outputs
When the over voltage is detected, the L-side FET is OFF
• Power good indicator pin (PGOOD)
• Integrated overcurrent protection with self recovery |
