SY8121 Overview
Description
SY8121 develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current. SY8121 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):140/130 mΩ
- 4.5-18V input voltage range
- 2A load current capability
- Instant PWM architecture to achieve fast transient responses
- Internal softstart limits the inrush current
