TPS60303DGSG4

TPS60303DGSG4 is a synchronous buck dc-dc converter, specifically designed to provide 3.0-A adjustable output current. It is categorized as a DC-DC switching regulator and lies in the voltage regulator family of PMICs. The device integrates a buck regulator that operates from an input voltage range from 1.5 to 5.5 V with a 3.0-A maximum switching current, creating a 0.6-V to 3.6-V output voltage range. The TPS60303DGSG4 features adjustable switching frequency which is user-selectable from 600 kHz up to three MHz bandwidth. Its switching frequency is set with a resistor connected between the RT/CT and GND pins.

TPS60303DGSG4 provides both current and thermal foldback protections that help protect the device from over-current conditions and thermal overload. The current foldback or overload protection prevents excessive current dissipation. The thermal foldback adjusts the switching frequency as a function of die temperature to prevent overload and thermal runaway condition. If a fault occurs, the device enters non-latching hiccup mode and the fault indicator is latched. An internal soft-start function is also provided with an adjustable two-setting delay.

The application fields of TPS60303DGSG4 mainly include industrial, automotive, telecom, computer peripherals and consumer electronics. With its low output noise and excellent ripple rejection, and its efficient operation, the TPS60303DGSG4 is well-suited for powering microprocessors, FPGAs, DSPs, and other digital circuitry. The device is also suitable for LCD and LED displays, lift power supply and engine switching power supplies, as well as step-up and step-down voltage converters, DC-DC converters for distributed power systems, and other applications that requires wide input range and low output current.

In summary, TPS60303DGSG4 is a high performance DC-DC buck converter which operates with an input voltage range of 1.5 to 5.5 V and an adjustable 0.6-V to 3.6-V output voltage range. It is integrated with current foldback protection and thermal foldback protection, as well as an adjustable two-setting delay. The device is suitable for most output currents and therefore can be applied in many application fields, such as industrial, automotive, telecom, computer peripherals, consumer electronics, LCD and LED displays, lift power supply, engine switching power supplies, and so on.
