SY8513 High Efficiency, 100V Input, 3A Asynchronous Step Down Regulator Advanced Design Specification General Description Features The SY8513 develops a high efficiency, current mode  Low RDS(ON) for Internal N-channel Power adaptive constant off time controlled, asynchronous FET(TOP): 150mΩ step-down DC/DC converter capable of delivering 3A  4.5-100V Input Voltage Range output current. The SY8513 operates over a wide input  3A Output Current Capability voltage range from 4.5V to 100V and integrates main  Adjustable Switching Frequency Range: switch with very low RDS(ON) to minimize the 100kHz to 500kHz conduction loss. The switching frequency is adjustable  Internal Soft-start Limits the Inrush Current from 100kHz to 500kHz using an external resistor. And  Hic-cup the device features cycle-by-cycle peak current Mode Output Short Circuit Protection  EN ON/OFF Control with Accurate Threshold limitation.  Cycle-by-cycle Peak Current Limit  0.8V± 1% Reference Voltage Accuracy Ordering Information  Compact Package: SO8E SY8513 ( ) □ □□□ Temperature Code App
