SY21286A
Overview
The SY21286A is a high efficiency synchronous buck converter operating over a wide input voltage range of 4.5V to 24V and capable of delivering up to 6A current. It integrates low RDS(ON) top and bottom MOSFETs to minimize the conduction loss.
- Low RDS(ON) for Internal MOSFETs: 28mΩ Top, 16mΩ Bottom
- Wide Input Voltage Range: 4.5V ~ 24V
- Adjustable Output Voltage: 0.6V ~ 12.5V
- High Duty Cycle Capable using On-Time Stretch
- 6A Continuous Output Current Capability
- 600kHz Pseudo-Constant Frequency
- ±1% Internal Reference Voltage
- Internal 1.2ms Soft-Start Limits the Inrush Current
- Constant On-Time and Ripple-Based Control to Achieve Fast Transient Responses
- Integrated 1.2Ω Bypass Switch
