Texas Instruments offers a wide range of power management products, including high efficiency dc-dc switchmode regulators. One versatile power management integrated circuit is the TPS62051DGSRG4. This device is a PMIC - Voltage Regulators - DC DC Switching Regulators designed for cost-sensitive industrial, automotive and other space-limited applications.

The TPS62051DGSRG4 is a constant frequency, synchronous, fixed-frequency, current-mode, step-down converter. It operates from an input voltage range of 4.5 V to 18 V and provides an adjustable output voltage from as low as 0.52 V to as high as the input voltage. Output current is adjustable up to 5 A.

This device features multiple operating modes, such as fixed frequency and pulse- skip mode (PSM), constant on-time mode (COT), and spread spectrum. This offers designers flexibility in applications such as Li-Ion or NiMH battery charging, power adapters, and power management on microcontrollers and other embedded systems.

The IC also features an adjustable switching frequency from 100 kHz to 2.2 MHz, allowing designers to optimize the components needed for their design. The IC utilizes current-mode control, cycle-by-cycle current limiting and over-temperature protection. Low quiescent current, reverse current protection, and lossless current sensing are also supported.

The TPS62051DGSRG4 has an operating temperature of -40°C to +125°C and is available in a 14-pin, 4 mm × 4 mm QFN package. The device is designed for operating up to 5 A load. This device is ideal for cost-sensitive industrial and automotive applications, as well as for a variety of other space-limited applications.

The TPS62051DGSRG4 is an efficient, cost-effective power management solution with adjustable switching frequency and multiple operating modes. It supports multiple operating modes, including fixed frequency and pulse-skip mode (PSM), constant on-time mode (COT), and spread spectrum, making it suitable for Li-Ion or NiMH battery charging, power adapters, and power management on microcontrollers and other embedded systems. The IC also features adjustable switching frequency and current-mode control, cycle-by-cycle current limiting, and over-temperature protection.
