The TPS610986DSET is a high efficiency, dual-input synchronous, step-down power module regulator integrated with two controller ICs, two MOSFET switches, one output inductor and a variety of protection devices. It incorporates a very low Iq power stage, which can provide a light load current in the sub-microamp range in the SLEEP mode, making the device ideal for low-power applications. The TPS610986DSET is suitable for use in many types of voltage regulation applications, such as digital and analog power supplies, as well as portable and mobile devices.

The TPS610986DSET operating principle is based on the switching-buck principle. In this type of voltage regulator, a feedback loop creates an output voltage that is regulated by adjusting the duty cycle of the pulses sent to the switch. The output voltage is monitored by a control circuit that triggers the switch if the voltage is too high or low. The switch then remains open or closed until the voltage returns to its preset level, so that the desired output voltage is maintained.

The two integrated controller ICs of the TPS610986DSET support two independent inputs, allowing the output voltage to be scaled to a wide range of voltages. The controllers also support many features such as over-current protection, thermal-shutdown protection, and soft-start control, making them ideal for cost-sensitive applications that require safety and reliability.

The integrated power stage of the TPS610986DSET includes two high-efficiency, low-side MOSFET switches and a single normally-off high-side switch, providing good efficiency and thermal performance without the need of an external control chip. The combination of two control ICs and two MOSFET switches results in a high efficiency power stage that is capable of high current output at a low quiescent current.

The TPS610986DSET also features an integrated output inductor, which helps to reduce external component count and reduces voltages losses, improving total system power efficiency. The inductor also helps reduce electromagnetic interference (EMI), providing improved noise immunity and ensuring that the device is compliant with a wide range of international standards.

In summary, the TPS610986DSET is a high efficiency, dual-input synchronous step-down power module regulator, suitable for a large number of voltage regulation applications, such as digital and analog power supplies, as well as portable and mobile devices. With its dual-mode controller, integrated power stage, integrated output inductor and several protection features, the TPS610986DSET provides excellent system power efficiency, noise immunity and safety.
