SY26056 Datasheet | Silergy

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 plex pensation, even with low-ESR ceramic output capacitors. Internal 18mΩ power and 10mΩ synchronous rectifier switches provide excellent efficiency for a wide range of applications, especially for low output voltages and low duty cycles. The SY26056 offers cycle-by-cycle current limit, input undervoltage lockout, internal soft-start, output undervoltage and overvoltage protection, and thermal shutdown to provide safe operation in all operating conditions. The SY26056 is available in a pact QFN3.5mm×4mm package.
