General Description
SY8121B develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current.
SY8121B 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):170/160 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.
- 2% 0.6V reference.
- RoHS Compliant and Halogen Free.
- Compact package: SOT23-6.
