EUP3286
6A, 30V, Synchronous Step-Down
Converter with Programmable Frequency
DESCRIPTION
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.
