SY26056 Continuous Source- or Sink-Current, 6A, 6V Input High-Efficiency Synchronous Step-Down Regulator General Description The SY26056 high-efficiency synchronous stepdown DC/DC regulator is capable of delivering 6A of continuous source or sink output current over a wide input voltage range of 0.8V to 6V.The output voltage is adjustable from 0.4V to 1.2V Silergy’s proprietary Instant-PWM™ fast-response, constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles) and responds to load transients within approximately 100ns, while maintaining a nearconstant operating frequency over line, load, and output voltage ranges. This control method provides stable operation without complex compensation, even with low-ESR ceramic output capacitors.
