4V to 14V or 2.375V to 14V with an external bias supply,

the LTM4624 supports an output voltage range of 0.6V to

5.5V, set by a single external resistor. Its high efficiency

design delivers 4A continuous, 5A peak, output current.

Only bulk input and output capacitors are needed.

The LTM4624 supports selectable discontinuous mode

operation and output voltage tracking for supply rail se-

quencing. Its high switching frequency and current mode

control enable a very fast transient response to line and

load changes without sacrificing stability.

Fault protection features include overvoltage, overcurrent

and overtemperature protection.

The LTM4624 is available with SnPb (BGA) or RoHS

compliant terminal finish.
