描述
BD70522GUL是一个降压转换器,具有180nA静态电流,支持高达500mA的输出电流。ULP(超低功率)模式的恒定开启时间(COT)控制提供了卓越的瞬态响应,并通过在10μA负载范围内提供卓越的轻载效率延长了电池寿命。输出电压可以通过VSEL引脚从9个预设电压中选择。当输入电压接近输出电压时,集成电路进入100%接通模式,开关操作停止。日本碍子株式会社的芯片型陶瓷二次电池“EnerCera®”与ROHM电源IC的超低静态电流技术“Nano Energy™”相结合,助力实现免维护物联网设备,构建超高效蓄电单元。EnerCera® × Nano Energy™ Collaboration Page

BD70522GUL  
General Description  
Key Specifications  
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.
