描述：TPS92512DGQR
TPS92512/TPS92512DGQR是具有集成 MOSFET 的 2.5A 降壓（降壓）電流調(diào)節(jié)器，用于驅(qū)動(dòng)大電流 LED。這些 LED 驅(qū)動(dòng)器可提供 42 V 和 60 V (HV) 輸入范圍，在用戶選擇的固定頻率下工作，具有峰值電流模式控制，并提供出色的線路和負(fù)載調(diào)節(jié)。TPS92512/TPS92512DGQRLED 驅(qū)動(dòng)器具有用于模擬和脈寬調(diào)制 (PWM) 調(diào)光的獨(dú)立輸入，可實(shí)現(xiàn)不折不扣的亮度控制，分別實(shí)現(xiàn)大于 10:1 和大于 100:1 的對(duì)比度。 PWM 輸入與低電壓邏輯標(biāo)準(zhǔn)兼容，可輕松連接到各種微控制器。使用 IADJ 輸入和外部 0 V 至 1.8 V 信號(hào)，模擬 LED 電流設(shè)定點(diǎn)可在 0 V 至 300 mV 范圍內(nèi)調(diào)節(jié)。
對(duì)于使用兩個(gè)或更多 TPS92512/TPS92512DGQRLED 驅(qū)動(dòng)器的多串應(yīng)用，內(nèi)部振蕩器可以由外部時(shí)鐘過(guò)驅(qū)動(dòng)，確保所有轉(zhuǎn)換器都在公共頻率下運(yùn)行，從而降低拍頻的可能性并簡(jiǎn)化系統(tǒng) EMI 濾波。具有遲滯的可調(diào)輸入欠壓鎖定 (UVLO) 可根據(jù)電源電壓條件靈活地設(shè)置啟動(dòng)/停止電壓。
TPS92512DGQR包括逐周期過(guò)流保護(hù)和熱關(guān)斷保護(hù)。它采用 10 引腳 HVSSOP PowerPAD™ 封裝。
