TPS62410DRCRG4 Application Field and Working Principle

The TPS62410DRCRG4 is an advanced DC-DC converter integrating a high-efficiency, logic-controlled, current-mode switch-mode power supply (SMPS) and an output voltage regulator. It is an excellent choice for applications that require a positive output voltage of up to 35 V and a nominal input voltage range of 3 to 18 V. It operates from a 3V to 18V input over an extended temperature range of -40°C to +125°C.

The TPS62410DRCRG4 provides a high level of integration and is compatible with wide range of input and output voltages. It includes a general-purpose control logic that can sense input voltage and output current and regulate them accordingly. It also includes an adjustable peak current limit that is adjustable with external components. The TPS62410DRCRG4 also contains an automatic thermal protection circuit that shuts down if the junction temperature exceeds a predetermined level.

Applications

The TPS62410DRCRG4 is suitable for applications that require a positive output voltage up to 35V. It is suitable for a wide range of applications, including DC-DC converter for distributed power distribution applications, solar panel energy harvesting applications and automotive power systems.

The TPS62410DRCRG4 is also suitable for point-of-load and point-of-use applications. It can be used to drive LED loads, as well as powering embedded voltage regulators, FPGAs, CPLDs, DSPs, microcontrollers and other ASICs.

Working Principle

The TPS62410DRCRG4 uses a current-mode, logic-controlled, switch-mode power supply to convert a regulated input voltage to a regulated output voltage. It incorporates two main components: an internal step-up DC-DC converter and an output voltage regulator. The internal step-up converter is comprised of an inductor, a sense resistor, a control logic, a power MOSFET, and a compensation circuit. The internal step-up converter works in current-mode and is operated by the control logic.

The control logic senses input voltage and output current and regulates them accordingly. When the input voltage drops below a certain threshold, the control logic will boost the voltage by switching the power MOSFET and converting the regulator output voltage to a voltage that is higher than the input voltage. This boosts the regulator output voltage to the desired level. The sense resistor ensures that the output current is regulated and the internal compensation circuit stabilizes the output voltage.

The TPS62410DRCRG4 also includes adjustable input voltage and output voltage settings, an adjustable peak current limit, and thermal protection circuitry. The adjustable peak current limit ensures that the device does not draw excessive current from the input and protects it from possible current spikes. The thermal protection circuit shuts down the device if the junction temperature exceeds a predetermined level. The TPS62410DRCRG4 also has integrated thermal shutdown and over-current protection and is UL 94 V-0 flammability rated.
