TPS60212DGSG4 is a synchronous step-down DC/DC converter based on Texas Instruments’ TPS60212 family whose powerful are very small in size with high integration. The application fields of TPS60212DGSG4 are varied and ranging from 4.5 to 26 V, such as automotive and industrial applications, mobile radios, avionics, fashion and man-machine interface systems, and transportation. Moreover, this device is suitable for those occasions where require high efficiency, advanced features, and superior accuracy.

TPS60212DGSG4 mainly works with two input power sources, respectively using additional application voltage and internal 1.6V Vref voltage as feedback voltage. The internal voltage references of this device are trimmed precision references: 1.6V Vref and -3.6V Vref, which provide a precise and stable output state. One of major advantages of TPS60212DGSG4 is its ability to provide ±1.0% total output voltage accuracy over the entire -40°C to +125°C temperature range. Meanwhile, its additional features such as the output current limit or short-circuit limit, overvoltage protection, and thermal shutdown further form the security for its applications.

In addition, TPS60212DGSG4 also provides comprehensive options to meet system design needs, including multiple adjustable output voltage settings from 0.8V to 3.7V, and adjustable switching frequency up to 2MHz – allowing for accurate power level adjustable for the application at hand. It is also featured with the Adjustable Average Current Mode Control and Low standby current-saving capabilities. In resume, the TPS60212DGSG4 is a complete family of dc/dc converters offering highest integration, efficiency and accuracy.

Speaking of its working principle, TPS60212DGSG4 is exactly a DC-DC regulator switch. It use inductor and capacitor as inductive storage element and two metal-oxide-semiconductor field-effect transistors (MOSFETs) as its switching elements. When the power switch is turned on, the inductor stores the energy of the primary power source and make the output voltage rise. When the power switch is turned off, the output voltage is discharged to the secondary side, and the output voltage is kept constant by controlling the primary switch.

In conclude, the TPS60212DGSG4 from Texas Instruments is an ideal choice not only for its powerful features but also for its superb accuracy, allowing for accurate power level adjustment for the application range from 4.5 to 26V, such as automotive and industrial applications, mobile radios, avionics, fashion, as well as man-machine interface systems and transportation.
