The LTM4623IY#PBF is a complete step-down switching mode µModule Regulator includes the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 4 to 20V or 2.375 to 20V with an external bias supply, the LTM4623 supports an output voltage range of 0.6 to 5.5V, set by a single external resistor. Its high efficiency design delivers 3A continuous output current. Only ceramic input and output capacitors are needed. The LTM4623 supports selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. 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 over temperature protection.
● Current mode control, fast transient response
● External frequency synchronization
● Multiphase operation with current sharing
● Output voltage tracking
● Power good indicator
● ±1.5% Total DC output voltage error
