Ultra Low Iq Buck Converter


BD70522GUL
BD70522GUL是一個降壓轉換器,具有180nA靜態電流,支援高達500mA的輸出電流。ULP(超低功率)模式的恒定開啟時間(COT)控制提供了卓越的瞬態回應,並透過在10μA負載範圍內提供卓越的輕載效率延長了電池壽命。輸出電壓可以透過VSEL引腳從9個預設電壓中選擇。當輸入電壓接近輸出電壓時,積體電路進入100%接通模式,開關操作停止。
Ultra Low Iq Buck Converter
產品敘述

The BD70522GUL is a Buck Converter featuring 180nA quiescent current and supports output current up to 500mA. The Constant ON-Time (COT) control with ULP (Ultra Low Power) mode provides superior transient response and extends battery life by providing excellent light load efficiency below 10µA load range. The output voltage can be selected from 9 pre-set voltages by VSEL pins. When the input voltage gets close to the output voltage, the IC enters 100%ON mode where the switching operation stops.
