ROHM BD9E202FP4-ZTL DC-DC Switching Synchronous Buck Regulator, Adjustable, 4.5 to 28Vin, 0.7-22.4V/2A Out, TSOT-23-CJ-6

BD9E202FP4-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 a good transient response. It includes internal phase compensation. It is used in applications such as home appliance products (i.e., air conditioners, refrigerators), secondary power supply and adapter equipment, and telecommunication devices.
