The TPS2066CDGNR PMIC is a switch-mode, advanced power management solution for core-voltage isolation, switching and conversion. It features a controllable positive gate drive, which can be used for synchronous-rectification operations, in addition to its automatically enabled low-side gate driver. The TPS2066CDGNR provides robust operation for Sequencing and Power System Power Good Applications. Application Field The TPS2066CDGNR is designed for use in high-performance, cost-effective transformer circuitry for DC to DC converters, such as those found in notebook, desktop and server power supplies. It is also a suitable part for isolated applications ranging from isolated output connectors in computers to isolated medical power systems. The TPS2066CDGNR can be used to control the supply of a wide variety of loads and devices, including LEDs, power MOSFETs, single-channel LCDs and discrete logic circuits. It can also be used to limit the output current of power supplies or used together with the TPS2065 driver to take advantage of its integrated slew-rate control. In addition, the TPS2066CDGNR is an ideal part for providing isolation and level shifting between systems, allowing the switching of signals such as voltage, current, or other digital signals without the need for isolators. Working Principle The TPS2066CDGNR is based on an integrated high-performance, high-efficiency half-bridge power switch. The half-bridge structure consists of two power MOSFETs connected in series. Depending on the inputs to the two MOSFETs, either one or both of the MOSFETs can be activated. The TPS2066CDGNR also features a high-side gate driver, which is controlled through its Gate Enable pin, and a low-side gate driver that is always enabled. The TPS2066CDGNR is commonly used as a power switch in devices such as DC-DC converters, power supplies and other power control applications. It is normally used as an H-bridge power switch with input devices such as microprocessors, analog controllers, or other digital devices. This type of circuit is useful because it can control the amount of power delivered to the load and the direction in which the power flows. The TPS2066CDGNR also features a slew-rate control input, which can be used to regulate the rate at which the output switches between high and low. This feature is useful for controlling the power delivered to the load and is especially useful for preventing too much power from being transferred at once. Conclusion The TPS2066CDGNR is a high-efficiency, low-cost power switch that is well-suited for a variety of applications. It is designed for use in core-voltage isolation, switching and conversion applications, as well as power distribution and sequencing. It can be used to limit the output current of power supplies and provide level shifting between systems. It also features a controllable positive gate drive and a high-side gate driver, and can also be used with the TPS2065 driver for slew-rate control.
