SY8253 Overview
Description
The SY8253 is a high efficiency 500 kHz synchronous step-down DC/DC converter capable of delivering 3A current. The SY8253 operates over a wide input voltage range from 4.5V to 23V 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): 105mΩ/50mΩ
- 4.5-23V input voltage range
- 3A output current capability
- 500 kHz switching frequency
- Instant PWM architecture to achieve fast transient responses
