EUP3288F
8A, 30V, Synchronous Step-Down Converter with Programmable FrequencyDescription
The EUP3288F is a synchronous, step-down constant on-time buck regulator capable of driving 8A continuous load current. The EUP3288F can operate with an input up to 30V and the output can be externally set down to 0.8V. The EUP3288F provides excellent transient response with constant on-time 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 EUP3288F is available in a 4mm x 4mm TQFN-23 package.
