SY2A26066
Description
The SY2A26066 is a high-efficiency synchronous stepdown DC/DC regulator featuring internal power and synchronous rectifier switches capable of delivering 6A of continuous output current over an input voltage range from 3V to 7V. Silergy’s proprietary Instant-PWM™ fast-response, constant-on-time (COT) control method supports high input/output voltage ratios (low duty cycles) and responds to load transients within approximately 100ns, while maintaining a near-constant operating frequency over line, load, and output voltage ranges.
