The very low no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC7818 features a precision 0.8V reference for the bucks, a 1.2V reference for the boost, and a power-good output indicator. The LTC7818 additionally features spread-spectrum operation which significantly reduces the peak radiated and conducted noise on both the input and output supplies, making it easier to comply with electromagnetic interference (EMI) standards.
The Analog Devices Inc. LTC7818 Triple Output Synchronous Controller is available in a 6mm x 6mm QFN-40 package.
