TPS60243DGKR is a high efficiency DC-DC buck switching regulator and is the latest offering from Texas Instruments (TI) optimized specifically for automotive applications. With an input voltage range up to 45V and up to 2A output current, it can regulate both positive and negative voltages, which makes it an ideal choice for automotive electronic system design. The TPS60243DGKR also provides excellent thermal performance, with a thermal shutdown temperature range of up to 140°C. This makes it well suited for tough environment and highly reliable performance.

The TPS60243DGKR is an integrated buck regulator for converting a wide input voltage range to regulated output voltages of 3.3V, 5V and adjustable outputs from 0.8V to 6V. It is designed for critical load applications that require load regulation, low power consumption and high efficiency. The TPS60243DGKR offers a wide range of features including soft-start and stepdown control, adjustable input current limit, output over-voltage protection, under-voltage lockout, run mode, and short-circuit protection.

The TPS60243DGKR is also a Constant On-Time (COT) based regulator, meaning it will automatically switch on/off at a defined frequency to regulate the output voltage. This makes the regulator robust and more efficient, reducing the switching losses when compared to conventional voltage regulation methods.

In summary, the TPS60243DGKR is an excellent choice for automotive applications that require voltage regulation over a wide input voltage range. Its COT based regulation scheme allows for improved efficiency and low switching losses, making it highly reliable and suited for tough environmental conditions.
