2.5V 至 22V 輸入、7.8A 開關(guān)電流高效降壓-升壓轉(zhuǎn)換器，適用于 USB-PD/PPS 應(yīng)用

MAX77859 是一款高效、高性能升降壓轉(zhuǎn)換器，適用于需要寬輸入電壓范圍（2.5V 至 22V）的系統(tǒng)。該 IC 在降壓模式下可提供高達 6A 的輸出電流，在升壓模式下可提供高達 4A 的輸出電流（VIN = 3.7V、VOUT = 5V）。該 IC 支持系統(tǒng)通過 I2C 串行接口動態(tài)改變輸出電壓。MAX77859A 具有 I2C 可調(diào)輸出限流值，分辨率為 50mA/步進（具有 10mΩ 檢測電阻），以支持 USB-C PPS 要求。MAX77859B 是非 PPS 版本，并針對低靜態(tài)電流進行了優(yōu)化。配備 MAX77859 的系統(tǒng)可為外設(shè)提供更高輸出電壓，實現(xiàn)快速充電，盡可能減少電纜/連接器 ? 寬輸入電壓范圍：2.5V 至 22V\n? 3.2V 至 16V，采用內(nèi)部反饋電阻?3.0V 至 20V，采用外部反饋電阻，參見表 1\n?
