TBD62083AFG is classified as a PMIC – Power Distribution Switches, Load Drivers. It is a voltage regulator with integrated input protection, current limiter and over-temperature protection. This device is suitable for both Step Down (Buck) and Step Up (Boost) applications and DC/DC applications. It can be used for voltage regulation of DC motor, LED lighting and other types of power conversion.

The TBD62083AFG is a single-chip switch mode power supply (SMPS) controller designed to provide stable voltage output combined with low power consumption and system noise. It features high current switching up to 80A and low output voltage ripple. The device is suitable for a wide range of applications including consumer electronics, automotive and industrial systems.

The TBD62083AFG is programmed to provide over-temperature protection and output overcurrent protection. Over-temperature protection locks the device and prevents it from operating. Output overcurrent protection monitors the load current of the load and shuts off the power supply (external power MOSFET) if the current exceeds the set limit. This behavior protects the load device from excessive current.

The working principle of the TBD62083AFG is based on a "current mode control" which maintains the output current of the device constant. A voltage reference generates a voltage which acts as the main control signal. The output current is sensed by an external shunt resistor and converted into a voltage. This voltage is then compared with the reference voltage and used to adjust the supply voltage. The voltage reference allows the device to provide high conversion efficiency and low output noise.

The TBD62083AFG is capable of high-current switching up to 80A with a maximum continuous output current of 8A. The power saving design includes a digital soft-start and self-adjusting frequency limiting, which helps reduce the start-up and running current while minimizing system noise. The device also features output voltage feedback to ensure that the voltage is maintained even during transient loads.

The TBD62083AFG is ideal for a wide range of applications including automotive, industrial, and consumer electronics. It is suitable for DC/DC converters, Step Down (Buck) and Step Up (Boost) converters, and other power conversion applications where accurate and efficient voltage regulation is required.
