TPS43061RTER is a High-Voltage DC/DC synchronous step-down controller with a switching frequency up to 1 MHz. It provides a simple, efficient, and cost-effective solution for a wide range of synchronous power supply design needs. The device features two switched-capacitor bypasses on each low-side switch for high capacitive loading, and a high-side buck-mode conversion. The device also includes an internal 14-bit DAC and an integrated buck controller.

TPS43061RTER has a broad range of applications, ranging from laptop and tablet computers to industrial, communications and computing systems. It is particularly well suited for powering systems that require high-power efficiency, such as systems with multiple cores or large amounts of memory. Furthermore, the device is designed to support multiple output voltages and to operate in either buck or CCM mode.

The TPS43061RTER has a working voltage range is 3.2V to 20V, input and 12V to 30V output. The current limit is adjustable up to 3A. The switching frequency is user-programmable from 0.5 to 1MHz and can be synchronized to an external clock. The device also supports soft-start and enables output current measurement using an external sense resistor.

The device uses an integrated synchronous buck controller to regulate the output voltage. The output voltage is selected using an on-board DAC and an external amplifier. The buck controller monitors the output voltage and adjusts the output current to maintain the desired output voltage. The switching frequency and pulse width are also adjustable, allowing designers to customize their power supplies as needed.

The device has an internal low-side MOSFET driver that works with an external high-side MOSFET driver to provide a high efficiency synchronous buck converter. The external driver is used to connect the high-side and low-side MOSFETs and to provide protection against current spikes. The buck converter is optimized for high power efficiency, providing an overall efficiency up to 94%.

The TPS43061RTER provides a wide range of features for power supply design, including soft-start, adjustable current limit and temperature compensation. The device also features two switches for bypassing the inductor during start-up. This ensures that the power supply can be started from no-load conditions and provides short-circuit protection. The device also provides fault monitoring and protection against undervoltage and overvoltage conditions.

In summary, the TPS43061RTER is a high-voltage synchronous step-down controller with a wide range of applications. It provides efficient power conversion and supports adjustable switching frequencies, current limits and a host of other features. The device is designed to offer high power efficiency, providing a low-cost and efficient solution for many power supply design needs.
