Description
SY8205 develops a high efficiency synchronous stepdown DC-DC converter capable of delivering 5A output current. SY8205 operates over a wide input voltage range from 4.5V to 30V 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): 70/40 mΩ
- 4.5-30V input voltage range
- Instant PWM architecture to achieve fast transient responses
- External softstart limits the inrush current
- Pseudo-constant frequency: 500kHz at heavy loads
- 5A continuous, 6A peak load current capability
- 1.5% 0.6V reference
- Output over current limit
- Output short circuit protection with current fold back
- Thermal shutdown and auto recovery
