bd9e202fp4-凯发k8一触即发
4.5v to 28v input, 2.0a integrated mosfet single synchronous buck dc/dc converterbd9e202fp4-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. bd9e202fp4-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.
