SY8284 Synchronous Step Down Regulator

The SY8284 develops a high efficiency synchronous step-down DC/DC regulator capable of delivering 4A current over a wide input voltage range of 4V to 23V. Silergy’s proprietary Instant-PWM™ fast-response, constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty .
