2.7V to 5.5V Input, 3.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9B307NF-Z is one of the BD9Bx07NF-Z series of single synchronous buck DC/DC converter with builtin low on-resistance power MOSFETs. It can provide current up to 3A. The output voltage can achieve a high accuracy due to ±1% reference voltage. It features fast transient response due to constant ontime control system. The Forced PWM Mode control reduces the output voltage ripple in the whole load range. Power Good function makes it possible for system to control sequence. It achieves the highpower density and offer a small footprint on the PCB by employing 6pins 1.5mm x 1.5mm small package. We also offer the lineup of products with Light Load Mode Control, as well as products with different Output Current.

- Evaluation Board - BD9B307NF-EVK-001
This Evaluation Board was developed for ROHM’s Single Synchronous Buck DC/DC Converter BD9B307NF-Z. BD9B307NF-Z is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. The output voltage can achieve a high accuracy due to ±1 % reference voltage. It features fast transient response due to constant on-time control system. The Forced PWM Mode control reduces the output voltage ripple in the whole load range. Power Good function makes it possible for system to control sequence. It achieves high power density and offers a small footprint on the PCB by employing 6 pins in a 1.5 mm x 1.5 mm small package.
