The SY2A26066 is a high-efficiency synchronous step-down 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. This control method provides stable operation without complex compensation, even with low-ESR ceramic capacitors.
Internal 22.1mΩ power and 8.1mΩ synchronous rectifier switches provide excellent efficiency over a wide range of applications, especially for low output voltages and low duty cycles. Cycle-by-cycle current limit, input undervoltage lock-out, internal soft-start, output undervoltage/overvoltage protection, and thermal shutdown provide safe operation in all operating conditions.
The SY2A26066 is available in a compact QFN2mmx3mm-14 package.
