數(shù)據(jù): TPS548B22 1.5V 至 18V VIN,4.5V 至 22V VDD,具有全差動傳感功能的 25A SWIFT? 同步降壓轉換器 數(shù)據(jù)表 (Rev. A)
TPS548B22器件是一款具有自適應導通時間D-CAP3模式控制的緊湊型單相降壓轉換器。該器件針對空間受限類電源系統(tǒng)而設計,可實現(xiàn)高精度,高效率和快速瞬態(tài)響應,易于使用,且使用的外部組件較少。
該器件采用全差動傳感和TI的集成FET ,高器導通電阻為4.1mΩ,低側導通電阻為1.9mΩ。此外,該器件還具備0.5%的精度和0.9V基準電壓,環(huán)境溫度范圍介于-40°C和+ 125°C之間。具有競爭力的特性包括:超低的外部組件數(shù),精準的負載和線路調節(jié),輸出電壓設定值精度,自動跳過或FCCM工作模式以及內部軟啟動控制。
TPS548B22器件采用7mm×5mm,40引腳,LQFN-CLIP(RVF)封裝(RoHs豁免)。
