n Pin Compatible with LTM4668A (0.6V to 5.5V
Output, 2.25MHz). The LTM®4668 is a quad DC/DC step-down µModule
(micromodule) regulator with 1.2A DC current per output. Outputs can be paralleled in an array for up to 4.8A
capability. Included in the package are the switching
controllers, power FETs, inductors and support components. Operating over an input voltage range of 2.7V to
17V, the LTM4668 supports an output voltage range of
0.6V to 1.8V. Only bulk input and output capacitors are
needed. The device supports frequency synchronization,
poly-phase operation, selectable Burst Mode operation,
100% duty cycle and low IQ operation. Its high switching
frequency and a current mode architecture enables a very
fast transient response to line and load changes without …
