TPS62619YFDT Application Field and Working Principle

The TPS62619YFDT is a series of synchronous DC-DC buck switching regulators from Texas Instruments. These regulators have an output voltage range from 0.58 V to 5.5 V and provide up to 4 A of output current. The device features a wide input voltage range of 2.4 V to 5.5 V, making it ideal for high-voltage systems that require a low-voltage output. The device also has a very low quiescent current of less than 2 µA and a high efficiency of up to 95%. In addition, the operating temperature range of -40 °C to 125 °C allows it to operate in a wide range of harsh environments.

The TPS62619YFDT is a synchronous buck regulator that uses the conduction of a low-value output MOSFET to regulate an output voltage (Vout) from a given input voltage (Vin). The MOSFET is driven by an internal oscillator, which is enabled when the enable (EN) pin is logic high. When the EN pin is low, the device is disabled and the output voltage is pulled down to ground. The operating frequency can be programmed using the frequency set pin (FREQSET). The regulator will then switch the MOSFET on and off to maintain the set frequency and the output voltage set by the voltage sense pin (VSENSE). The error amplifier ensures the output voltage is regulated within the specified voltage tolerance.

The TPS62619YFDT features a low operating current of 2 µA which helps to keep the power loss during periods of high inactivity to a minimum. The device uses a very small area and is capable of very high peak currents up to 4 A, ensuring excellent efficiency and power delivery. The device also features advanced features such as frequency synchronization, programmable soft-start and output current limiting, making the TPS62619YFDT suitable for a variety of high-performance applications. These features make the TPS62619YFDT an excellent choice for high-performance, space-constrained, low-voltage applications.

In conclusion, the TPS62619YFDT series of synchronous DC-DC buck switching regulators from Texas Instruments are an ideal choice for providing a low-voltage output with a wide input voltage range and a very high efficiency. The very low quiescent current and the advanced features such as frequency synchronization and soft-start guarantees excellent performance in a wide range of applications. With its small size and high peak current capabilities, the TPS62619YFDT can be used in space-constrained high-performance systems.
