The TPS62135RGXT is a DC to DC switching regulator, developed and provided by Texas Instruments. It is designed to be an efficient, high-power density solution for power management applications. The TPS62135RGXT is a step-down switching regulator that can provide an adjustable output voltage up to 1.2V with accuracy of ± 2.5%. It has a fixed frequency buck switching regulator that can be set to one of two preset frequencies: 500kHz or 1MHz. The TPS62135RGXT has low quiescent current and high switching frequency allowing for a very small, efficient solution. When compared to linear regulators, the TPS62135RGXT offers higher efficiency, higher switching frequency and a smaller form factor.

The TPS62135RGXT is an ideal solution for those applications that require a high-power density, low cost, and low noise DC-to-DC buck regulator. The device is optimized for applications that require a wide input supply range, such as handheld devices, radios, lighting control systems and automotive applications. The TPS62135RGXT also features programmable output voltage and current limit protection, a very low shutdown current, and an adjustable switching frequency.

The TPS62135RGXT operates by employing a fixed frequency buck switching converter. This type of converter typically uses two transistors (a low-side and a high-side switch) that are toggled at a fixed frequency to regulate the output voltage. The duty cycle of the switching converter is adjusted to achieve the desired output voltage. The frequency of the converter can be adjusted by varying the frequency modulation bias voltage, which directly affects the switching frequency. A higher switching frequency allows for greater efficiency and a smaller solution size, but also increases system noise and requires additional measures to be taken to reduce EMI.

The TPS62135RGXT has a wide range of operating temperature, up to 85°C. It also has a low shutdown current of 10µA and very high efficiency, with typical values of up to 91%. This makes the TPS62135RGXT an ideal solution for power management applications in space and weight restricted applications, such as portable device and automotive applications. The TPS62135RGXT has several protection features, including overvoltage, overcurrent, and short-circuit protection. These features, combined with the highly efficient switching frequency, make the TPS62135RGXT an excellent choice for integrated solutions.
