TPS62026DRCRG4 is a DC-DC switching regulator designed to provide the best power efficiency and solution size for applications with the strictest constraints on power consumed. It is a member of Texas Instruments\' family of non-synchronous buck switching regulators, specifically designed to offer excellent efficiency and flexibility in a very small footprint. It is a low input voltage, low output voltage, and low power synchronous step-down converter.

The TPS62026DRCRG4 can provide up to 3A of continuous output current with a supply voltage range of 1.62V up to 5.5V and it supports a wide output voltage range of 0.6V to 4.7V for both adjustable and fixed output regulation. It is also capable of providing a power saving feature. The device operates in pulse frequency modulation (PFM) or pulse width modulation (PWM) mode, allowing for high efficiency under varying load conditions.

The TPS62026DRCRG4 also features a very fast transient response, a voltage feedback reference with 0.5% accuracy over temperature, an integrated output voltage selection, an over-current protection system, an on/off logic control, and over-voltage protection (OVP) and short circuit protection. The device is available in the VQFN-6 (ETC package) and VSSOP-8 (EDAP package), making it the ideal choice for space-constrained applications.

The operating principle of the TPS62026DRCRG4 is based on the common synchronous buck converter topology, with an internal high-side and low-side MOSFETs pass element. This circuit works by rectifying an alternating current into a direct current (DC). The input voltage is stepped down, and the output is regulated by varying the duty cycle of the switching frequency.

The device includes an internal oscillator, which can be adjusted to a variety of operating frequencies. The frequency can be adjusted by varying the value of the external resistor or capacitor connected to the RT/CT pin. The higher the output voltage, the lower the switching frequency should be set.

The TPS62026DRCRG4’s application field includes power management in portable and non-portable applications including smartphones, tablets, industrial & instrumentation equipment, personal medical devices and Avionics. It can also be used for regulated point-of-load applications in battery- or AC-powered applications.

In conclusion, the TPS62026DRCRG4 is an ideal solution for portable and non-portable applications that require a low input voltage, and low output voltage, and low power synchronous step-down converter with high efficiency, high power density, fast transient response, and integrated protection features.
