SY8388A Description
SY8388A develops a high efficiency synchronous stepdown DC/DC regulator capable of delivering 8A current over a wide input voltage range of 4V 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...
