资 源 简 介

 

Battery powered applications that have a signifi cantamount of time in standby mode, require electrical circuitsto operate with a low quiescent current to preserve batterylife. The LTC3835 synchronous step-down controlleris an excellent solution with its ultralow quiescent current(80μA). Other features make it uniquely qualifi ed tosatisfy the needs of automotive applications. A wide 4Vto 36V input voltage range protects the supply againsthigh input voltage transients and is compatible with lowvoltage cold crank conditions. The constant frequencycurrent-mode architecture with high-side inductor current
