The TPS62088YFPT is a synchronous step-down DC/DC regulator that addresses the needs of a broad variety of applications, such as FPGA and microcontrollers. This energy-efficient device operates over a wide input supply range, providing up to 6 A of continuous output current, and can be configured as either a basic step-down or a buck-boost regulator. The regulator features an internal synchronous P-channel MOSFET switch and an integrated LDO to minimize external component count while offering improved efficiency over popular off-the-shelf buck regulator solutions. Its low operating current and low quiescent current in light load applications make it suitable for both battery- and USB-powered designs.

Application fields for the TPS62088YFPT include automotive, industrial and consumer applications, such as microcontrollers, FPGAs, DSPs, and low-noise regulators for analog circuits. The advantages of the device include strong ESD capability and robust protection features, minimizing external component count, low ripple and noise and high efficiency, high operating frequency, low power consumption, and wide input voltage range.

The TPS62088YFPT features a 2 MHz switching frequency, allowing small output and input cap sizes, while achieving better than 1 % voltage accuracy. The device has an adjustable output range from 0.6 V to 5.5 V and an input voltage range of 2.3 V to 6 V. It has a fixed 220 kHz switching frequency and can be synchronized to an external clock up to 500 kHz. The device\'s output current is regulated with a 100 mV feedback voltage. The device is fully protected against current-limit, short-circuit, thermal-shutdown, undervoltage, and overvoltage conditions.

The working principle of the TPS62088YFPT is based on a buck regulator configuration. It contains an internal low on-resistance synchronous P-channel MOSFET switch as the main power switch. An integrated LDO is used to reduce the power loss and minimize the external component count. The device also integrates output voltage sensing and compensation, enabling high-accuracy voltage regulation. It works by connecting a switching MOSFET between the input voltage and the output voltage, where the MOSFET is periodically controlled by a control circuit. It also includes an oscillator circuit to generate a switching frequency. The outputs of the oscillator and comparator are then used to control the MOSFET. During the power-on state, the device operates in a step-down or buck mode, where the input voltage is higher than the output voltage. During the power-off state, it operates in a step-up or boost mode, where the input voltage is lower than the output voltage.

In summary, the TPS62088YFPT is a highly efficient synchronous step-down DC/DC regulator, suitable for a wide range of applications. Its low operating current, low quiescent current in light load applications, strong ESD capability, and robust protection features make it suitable for both battery- and USB-powered designs in automotive, industrial and consumer applications.
