MAX16610A Series

The MAX16610/MAX16610A ICs are highly integrated, scalable, controllers for a switched tank converter (STC) topology. The STC provides highly efficient zero-current switching (ZCS) voltage conversion from a 60V–40V input bus to an intermediate bus voltage. The intermediate bus voltage is unregulated and is approximately a quarter of the input voltage.The 4:1 STC topology has 10 FETs that need to be driven, with only 3 of the FETs connected to ground. The MAX16610/MAX16610A provide an extremely dense solution with integrated drivers and generation of floating supplies.An adaptation algorithm tunes the STC on-times to maintain ZCS, regardless of variations in and tolerances of the STC components (e.g., temperature coefficient, aging, and voltage derating). With the adaptation algorithm, a MAX16610/MAX16610A-controlled STC can use Class II capacitors in the resonant tanks to save on cost and improve efficiency compared to Class I capacitor designs.Multiple fault protection features prevent damage to the STC converter and downstream components.ApplicationsDDR MemoryHigh-Power VR13.HC CPUsMachine Learning ASICs and Accelerator CardsNetworking ASICs
