ROHM BD9E200FP4-ZTL DC-DC Switching Synchronous Buck Regulator, Adjustable, 4.5 to 26Vin, 0.7 to 20.8V/2A Out, TSOT-23-6

BD9E200FP4-ZTL 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. It 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. Application includes home appliance Products (i.e., air conditioner, refrigerator), secondary power supply and adapter equipment, telecommunication devices.
