SY21245 - Synchronous Buck Converter

Key Features

  • The SY21245 high efficiency synchronous Buck converter can deliver 8A output current over a wide input voltage range from 4V to 40V. The SY21245 employs a constant on-time and ripple-based control strategy to achieve fast transient responses. The SY21245 integrates the top MOSFET and bottom MOSFET with very low RDS(ON) to minimize the conduction loss. Silergy’s constant on-time (COT) ripple-based control method supports high input/output voltage ratios (low duty cycles), and fast transient resp.

SY21245 High Efficiency, 8A, 40V Input Synchronous Buck Converter General Description Features The SY21245 high efficiency synchronous Buck converter can deliver 8A output current over a wide input voltage range from 4V to 40V. The SY21245 employs a constant on-time and ripple-based control strategy to achieve fast transient responses. The SY21245 integrates the top MOSFET and bottom MOSFET with very low RDS(ON) to minimize the conduction loss. Silergy’s constant on-time (COT) ripple-based control method supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load, and output voltage ranges.
