The SP6132HEU-L/TR is a highly integrated, multi-phase DC/DC controller designed for applications requiring two or more voltage rails in parallel. This particular type of power management integrated circuit (PMIC) is considered a DC/DC switching controller, as it functions by modulating the voltage of an power supply per the desired output voltage. This process is regulated by the use of feedback loops with an internal high accuracy voltage reference.

The SP6132HEU-L/TR was designed with power-saving and reliability as top priorities, while offering a high level of integration and flexibility. This product includes a dedicated soft-start circuit, as well as automatic reset and power-on reset monitors. Moreover, its proprietary Predictive Gate Drivers technology (PGDT) provides instant gate drive for the external MOSFET, resulting in a faster response to the load transient requirements. This controller is also universal input capable, allowing for the use of 4.5V to 26V power supplies, and is capable of switching frequencies up to 1.3MHz.

The integrated features of the SP6132HEU-L/TR make it a suitable choice for many types of applications requiring multiple power rails in parallel. This would include both consumer and industrial applications, such as computing, communications, servers, storage, power line communications (PLC), telecommunications, automotive electronics, and various consumer appliances. One of the primary advantages of the multi-phase approach is that the current can be equally divided amongst the rails, resulting in lower thermal stress and decreased output voltage ripple.

The working principle of the SP6132HEU-L/TR is based on an internal voltage reference. This reference sets the switching frequency of the device, and is also used to compare with the output voltage as measured by a feedback loop. If the output voltage becomes lower than the reference voltage, the IC will increase voltage by increasing the duty cycle, while if the output is higher, then the duty cycle is lowered.

The SP6132HEU-L/TR is designed to be highly accurate in controlling voltage, having a peak current accuracy of 1.5% and a steady state current accuracy of 3%, and is capable of delivering up to 5A of current for each phase. Moreover, it features variable switch resistance, allowing it to adjust quickly to changing load requirements. All of these capabilities combine to make the SP6132HEU-L/TR an ideal choice for power management designs requiring two or more voltages in parallel.
