The Cypress S6AP412A and S6AP413A are non-isolated multiple channel DC-DC converters and use software to enable flexible and precise power supply sequence control. Embedded systems equipped with the latest SoCs and FPGAs often require control of a 3- or 4-channel power supply sequence when starting up or disconnecting the power supply. In addition, by enabling multiple channel power supply within a single chip, the BOM for the power supply block can be reduced and the board surface area is reduced up to 30%.

These new PMIC solutions also use the common Inter-Integrated Circuit (I²C) communication interface to enable switching to an optimum voltage according to the SoC operation mode and process conditions while maintaining the output, and are thus able to support both Dynamic Voltage Scaling (DVS) and Advanced Supply Voltage (ASV) technologies. The S6AP41x series also supports reduced power consumption by systems through precision control of the voltage used by cutting-edge SoCs.

Easy preparation of startup and disconnect sequence for the power supply line: The latest systems require optimal control of the 3-channel power supply sequence when starting up and disconnecting, and this product can freely and flexibly control various sequences through software control. In addition, a method to buck-boost is adopted for the channel used for peripheral devices, and a stable output can be achieved even with a single-cell lithium-ion battery and a 3.3 V input. By adopting this product, systems that require different sequences can be supported while maintaining the same hardware.
