RTQ2072A-QT/RTQ2072B-QT 是一款高度整合的 PMIC,專為車用攝影機應用而設計。它包含三個降壓轉換器與一個高 PSRR 低壓差 (LDO) 穩壓器。高電壓降壓轉換器可在高達 18.5V 的輸入電壓範圍內運作,適用於 Power Over Coax (POC) 連接。兩個低電壓降壓轉換器可提供固定輸出電壓。所有降壓轉換器皆以強制固定頻率 PWM 模式運作。LDO 輸出電壓可透過外部電阻輕鬆設定。RTQ2072A-QT/RTQ2072B-QT 支援 10 種電源時序,可透過電阻進行設定。此 ICQ 採用 WETD-VQFN-16L 3x3 封裝,具備凹點引腳型可潤濕側翼。建議接面溫度範圍為 −40°C 至 150°C,建議環境溫度範圍為 −40°C 至 125°C。
