AN-SY8105 Overview
Description
The SY8105 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 5.0A current. The SY8105 operates over a wide input voltage range from 4.5V to 18V 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): 40mΩ/26mΩ
- 4.5-18V input voltage range
- 5.0A output current capability
- 500 kHz switching frequency
- Instant PWM architecture to achieve fast transient responses
