EUP3286F
6A，30V，頻率可調的同步降壓型DC-DC轉換器Description
The EUP3286F is a synchronous, step-down constant on-time buck regulator capable of driving 6A continuous load current. The EUP3286F can operate with an input range from 4.5V to 30V and the output can be externally set down to 0.8V. The EUP3286F provides excellent transient response with constant ontime control method while maintaining a nearly constant frequency. The switching frequency can be externally programmed from 100KHz to 1MHz.
Fault condition protection includes VIN under-voltage lockout, cycle-by-cycle current limiting, output overvoltage protection, output under-voltage protection, as well as thermal shutdown. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup.
The EUP3286F is available in a 4mm x 4mm TQFN-23 package.
