Datasheet Summary
High Efficiency, 16V/20A Synchronous Step-down Regulator
General Description
The SY21720 is a high-efficiency synchronous step-down DCDC regulator featuring internal power and synchronous rectifier switches capable of delivering 20A of continuous output current over a wide input voltage range, from as low as 2.9V up to 16V. The output voltage is adjustable from 0.6V to 5.5V.
Silergy’s proprietary Instant-PWM™ fast-response, constanton-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles) and responds to load transients within ~100ns while maintaining a near constant operating frequency over line, load and output voltage ranges. This control...
