Description: Synchronous Step Down Regulator

Features

* Low RDS(ON) for Internal Switches (Top/Bottom): 85/35mΩ
* Wide Input Voltage range: 4~23V
* Instant PWM Architecture to Achieve Fast Transient Responses
* Internal 600µs Soft-start Limits the Inrush Current
* Pseudo-constant Frequency: 500kHz
* 4A Output Current Capability

Applications

* especially for low output voltages and low duty cycles. SY8284 also integrates a bypass switch which allows the IC to be powered by external DC source. Cycle-by-cycle current limit, input under voltage lock-out, internal soft-start, output under voltage protection and over voltage protection, and t
