TCS4103
Ultra-Low Quiescent Current Buck Converter
产品描述
The TCS4103 series is a high efficiency synchronous step-down converter featuring typical 360 nA quiescentcurrent. lt provides high efficiency at light load down to 10 pA. lts input voltage ranges from 2.2 V to 5.5 V andprovides eight programmable output voltages between 1.2 V and 3.3 V while delivering output current up to600 mA, peak to 1A(TCS4103)/400mA, peak to 0.5A (TCS4103A).
The Adaptive-Constant-On-Time (ACOT) operation with internal compensation allow the transient responseto be optimized over a wide range of loads and output capacitors.
The TCS4103 is a available in WLCSP8(0.9 x1.6 ,0.4 pitch) package
