SY8386 Description
The SY8386 develops a high efficiency synchronous step-down DC/DC regulator capable of delivering 6A current over a wide input voltage range of 4.5V to 24V. Silergy’s proprietary Instant-PWM™ fast-response, constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load and output...
