SY8386 Overview
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 voltage ranges.
Key Features
- Low RDS(ON) for Internal Switches (Top/Bottom): 38/19mΩ
- Wide Input Voltage Range: 4.5~24V
- Integrated Bypass Switch: 1.2Ω
- Instant PWM Architecture to Achieve Fast Transient Responses
- Internal Soft-start Limits the Inrush Current
