BD9E304FP4-LBZ (Under Development)
4.5V to 36V Input, 3.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter

This is the product guarantees long time support in Industrial market. BD9E304FP4-LBZ is a single synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. The Light Load Mode control provides excellent efficiency characteristics in light-load conditions which make the product ideal for equipment, and devices that demand minimal standby power consumption. BD9E304FP4-LBZ is a current mode control and features good transient response. Phase compensation can also be set easily. It achieves the high power density and offers a small footprint on the PCB by employing small package.
