SGM61111 3V to 17V, 1A Synchronous Buck Converter with AHP-COT Control GENERAL DESCRIPTION The SGM61111 is a high-frequency, synchronous Buck converter optimized for simple and quick application to high density designs. High output voltage accuracy and fast transient response along with small LC output filter elements are easily achievable with the 2.1MHz (TYP) switching frequency and the AHP-COT control. The 3V to 17V input voltage range makes this device a suitable choice for both 12V input power rails and the battery powered applications including Li-Ion batteries. It supports 100% duty cycle operation and can provide 1A continuous current to its adjustable or fixed output voltage versions. The enable input (EN) and powergood output (PG) pins provide power sequencing capability.
