BD9E105FP4-Z (Under Development)
4.5V to 28V Input, 1.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter

BD9E105FP4-Z 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. BD9E105FP4-Z is a current mode control DC/DC converter and features good transient response. It includes internal phase compensation. It achieves the high power density and offers a small footprint on the PCB by employing small package.
