TPS62737RGYT Application Field and Working Principle

The TPS62737RGYT is a synchronous, step-down DC-DC converter and buck regulator solution for low-power applications. The device provides efficient and adjustable step-down conversion in a small space-saving package. It is fabricated in a high-voltage, low-power 0.35um process, giving it excellent power efficiency, transient response, and load regulation characteristics. The step-down regulator operates with very low loss over a wide input voltage and load current range.The TPS62737RGYT is designed for applications such as handheld and portable consumer electronics, wireless communications products, wireless industrial control, battery-powered home appliances, and automotive infotainment systems. Its low-power mode and selectable low-quiescent current enable any device powered by battery or a system main source to extend battery life and reduce bill-of-materials (BOM) cost. The TPS62737RGYT is available in a space-saving 6-lead 2x3 mm package with an operating temperature range extending from -45°C to +125°C in a Pb-free (RoHS compliant) package.

Working Principle

The TPS62737RGYT is a synchronous, step-down DC-DC converter and buck regulator solution. It is a current-mode regulator capable of providing high efficiency over a wide input voltage and load current range. It uses a pulse width modulated scheme, where the duty-cycle is proportional to the difference between the input and output voltages.The TPS62737RGYT is designed to operate over a wide range of frequency, making it well-suited for low-power applications. The frequency can be synchronized to an external clock or oscillator, or synchronized internally to the rectified input voltage. The switch high-side and low-side MOSFETs are integrated into the package and do not require external drivers.The TPS62737RGYT employs adaptive on-time control to reduce switching losses at light loads. When the device enters a light-load state, the on-time reduces and maintains an 80% duty cycle for optimal light-load efficiency. This keeps the ripple voltage in check and reduces the output voltage ripple. The TPS62737RGYT also provides selectable quiescent current, allowing it to maintain high efficiency even at light-load conditions or when powered off a main source.The integrated soft-start circuitry helps reduce inrush current and prevents any overshooting of the output voltage during start-up. The TPS62737RGYT also features an adjustable 5V digital rail OUThyst to accommodate different levels of battery voltage.Overall, the TPS62737RGYT is an efficient, high-performance buck regulator solution for Low-Power applications, such as handheld and portable consumer electronics, wireless communications products, wireless industrial control, battery-powered home appliances, and automotive infotainment systems.
