DC1245A - LTM4616EV | Low Voltage Dual 8A or Single 16A uModule Regulator

Demonstration circuit 1245A features the LTM®4616, the high efficiency, high density, dual output switch mode power module. The rated load current is 8A for each channel, while derating is necessary for certain VIN, VOUT, and thermal conditions. By applying a clock signal to the CLKIN pin, the module’s switching frequency may be synchronized from 0.75MHz to 2.25MHz. The same clock frequency is available at the CLKOUT pin with the phase relationship between CLKIN and CLKOUT determined by the PHMODE pin. This feature can be used not only to reduce undesirable frequency harmonics but also to parallel the two channels of LTM4616 or even multiple LTM4616s and LTM4608s to provide higher output currents.
