TPS40041DRBR Application Field and Working Principle
The TPS40041DRBR is a DC DC switching controller with integrated FETs (field-effect transistors) with high output voltage accuracy. Its features make it an ideal choice for a variety of applications, ranging from automotive, industrial and consumer electronics to a wide range of general purpose applications.
Features
The TPS40041DRBR device has a wide array of features and advantages that make it a great choice for efficient power conversion applications. The device offers a wide operating range from 1.6V up to 48V. It also has an adjustable switching frequency of up to 1.2MHz. It integrates advanced control circuitry consisting of a Fully Synchronous PWM Controller along with an adjustable current-limit for improved control. It also includes integrated power FETs with low on-resistances and loss optimized gate drive stages.
The TPS40041DRBR can also accommodate a variety of application needs including operating temperature range of -40°C to +85°C, high efficiency operation with peak efficiencies reaching up to 95%, and off-line operation. The device also has full protection from overvoltage conditions, undervoltage lockout (UVLO) and a 10mS auto-restart after a fault.
Applications
The TPS40041DRBR is suitable for use in a variety of DC to DC conversion scenarios. It is ideal for high current applications such as Automotive/Industrial power applications, Battery/Energy storage systems, Grid interfacing applications, Tesla battery packs, and solar applications. It also has a wide range of applications in consumer electronics, such as Virtual Reality (VR) headsets, tablets, wearables, and smartphones.
Working Principle
The TPS40041DRBR device operates in accordance with a synchronous buck converter operating principle. A switch controllable by a PWM signal controls a buck converter circuit consisting of a high-frequency transformer, a primary switch and an inductor. When the switch is on, a transistor (such as an insulated gate bipolar transistor, or IGBT) conducts current from the secondary side of the transformer and through the inductor. As current ramps up in the inductor, a magnetic field builds, storing energy. When the switch turns off, the magnetic field collapses and energy is released, allowing current to flow to the output of the converter.
The PWM signal from the controller modulates the switching frequency and duty cycle to control the output voltage and current. The TPS40041DRBR controller also has an adjustable current limit and is configured to operate in current limit or frequency fold back mode. The controller also features under-voltage lockout (UVLO ), over-voltage protection (OVP ) and short-circuit protection (SCP ), ensuring reliable and safe operation.
Conclusion
In conclusion, the TPS40041DRBR is a robust, high performance DC DC switching controller with integrated FETs. It is ideal for use in a wide range of applications ranging from automotive, industrial and solar applications to consumer electronics. Its wide range of features such as its adjustable switching frequency, wide voltage range and efficient operation make it an ideal choice for power conversion applications requiring low-voltage, high-current and high-efficiency power solutions.
