3V to 17V, 300mA Buck Converter with Adjustable Enable Threshold and Hysteresis
The SGM61103 is an easy-to-use synchronous Buck DC/DC converter optimized for low-power applications. A high switching frequency of 1MHz (TYP) allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by using AHP-COT control topology.
With its wide operating input voltage range of 3V to 17V and low quiescent current, SGM61103 is ideally suited for battery-powered systems. The SGM61103 works in power-save mode to ensure the highest efficiency at light load conditions.
The SGM61103 supports up to 300mA continuous output current at wide output voltages between 1.2V and 10V. Lower-power EN comparator with precise threshold and hysteresis can be used as the input supply voltage supervisor (SVS). More hysteresis is possible by combining with EN_HYS pin. PG pin is also provided as output voltage indicator.
The SGM61103 is available in a Green TDFN-2×2-8AL package.
