SY8208A Overview
Description
The SY8208A develops a high efficiency synchronous step-down DC-DC regulator capable of delivering 8A continuous, 16A peak current. The SY8208A operates over a wide input voltage range from 4V to 28V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- Low RDS(ON) for internal switches (top/bottom): 20/10 mΩ
- Wide input voltage range: 4-28V
- Instant PWM architecture to achieve fast transient responses
- Internal 400uS softstart limits the inrush current
- Pseudo-constant frequency: 800kHz
- 8A continuous/16A peak output current capability
- ±1.5% 0.6V reference
- Programmable peak current limit
- Power good indicator
- Output discharge function
