數據: TPS548D22 1.5V 至 16V VIN、4.5V 至 22V VDD、40A 且具有全差分感應功能的SWIFT? 同步降壓轉換器 數據表 (Rev. D)
TPS548D22器件是一款緊湊型單通道降壓轉換器,具有自適應導通時間D-CAP3模式控制。該器件專為高精度,高效率,快速瞬態響應,易于使用,外部組件較少且空間受限的電源系統而設計。
該器件采用全差分感應和TI集成FET,高側導通電阻為此外,該器件還具有0.5%的精度和0.9V基準電壓,環境溫度范圍介于-40°C和+ 125°C之間。具有競爭力的特性包括:極少的外部組件數,精確的負載調節和線路調節,自動跳躍或FCCM工作模式以及內部軟啟動控制。
TPS548D22器件采用7mm×5mm,40引腳,LQFN-CLIP (RVF)封裝(RoHs豁免)。
