Datasheet Summary
High-Efficiency, Fast-Response, 9A Continuous/14A Peak, 24V Input, Synchronous Step-Down Regulator with ±1A VTT LDO and ±10mA Buffered Reference
General Description
The SY21240 high-efficiency synchronous step-down DC/DC regulator is capable of delivering 9A continuous/14A peak current over a wide input voltage range of 4V to 24V. It provides a plete power supply with the highest density for DDR3, DDR3L, LPDDR3, and DDR4 memory. The included sink/source VTT LDO can deliver ±1A output current.
Silergy’s constant on-time (COT) ripple-based control strategy supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near-constant...
