SY8493 Overview
Description
The SY8493 develops a high efficiency, current mode adaptive constant off time controlled, asynchronous step-down DC/DC converter capable of delivering 3A output current. The SY8493 operates over a wide input voltage range from 4.5V to 60V and integrates main switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- Low RDS(ON) for Internal N-channel Power FET(TOP):150mΩ
- 4.5-60V Input Voltage Range
- 3A Output Current Capability
- Adjustable Switching Frequency Range: 100kHz to 500kHz
- Internal Soft-start Limits the Inrush Current
