TPS60212DGSR is a 3.3V, 55mA fIxed-frequency, synchronous buck converter optimized for power management in portable system applications. It integrates a high-side switch, low-side switch, supply voltage regulator, and output voltage feedback loop. It is capable of smoothly transitioning from step-down to step-up or reverse-battery mode.

The chip belongs to the category of DC-DC switching regulators which are found in a wide range of applications, including computers, portable electronics, and automotive applications. DC-DC switching regulators are used when a DC output voltage needs to be generated from a DC input voltage, at a higher or lower voltage than the input. It is also used when power is to be switched between two sources at different voltages.

The TPS60212DGSR is an integrated circuit with an input voltage range of 1.8 V to 5.5 V, an output voltage adjustable from 0.75 V to 3.3 V, and a maximum output current of 55 mA. It employs a fixed-frequency synchronous buck converter, utilizing internal n- and p-channel MOSFETs to offer a high level of efficiency. It has an integrated low-side reference current-steering PWM controller, and a low quiescent current internal voltage regulator for low output ripple and reduced harmonics.

The TPS60212DGSR features reverse-battery protection, input overvoltage protection, as well as output over-/under-voltage protection. It also has an active high-side and low-side current-monitoring circuit, enabling protection against over-current conditions. The chip is RoHS compliant, and is available in a 6-pin SOT-23 package.
