EUP3286
6A, 30V, Synchronous Step-Down Converter with Programmable FrequencyDescription
The EUP3286 is a synchronous, step-down constant on-time buck regulator capable of driving 6A continuous load current. The EUP3286 can operate with an input range 2.7V to 30V and the output can be externally set down to 0.8V. The EUP3286 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 over-voltage protection, short-circuit protection, as well as thermal shutdown. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup.
The EUP3286 is available in a 4mm x 4mm TQFN-23L package.
