SY8286B Overview
Description
The SY8286B develops a high efficiency synchronous step-down DC/DC regulator with 3.3V fixed output voltage and 6A current rating. The device 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): 38/19 mΩ
- Wide Input Voltage Range: 4-23V
- 3.3V LDO with Individual Enable Control and Bypass Switch
- Integrated Bypass Switch: 1.5Ω
- Instant PWM Architecture to Achieve Fast Transient Responses
- Internal 1.2ms Soft-start Limits the Inrush Current
- Pseudo-constant Frequency: 600kHz
- 6A Output Current Capability
- +/-1.5% Output Voltage Accuracy
- Power Good Indicator
