The TPS40060PWPR is a DC DC switching controller made by Texas Instruments that offers advanced features and range of programmable parameters. This chip is suitable for low-power applications such as mobile phones, portable computers, tablets and similar mobile devices. It offers an integrated deep sleep mode that helps reduce system current consumption.

The TPS40060PWPR operates in step-up, step-down, and buck-boost switching topologies. It is capable of regulating output voltages from 0.6V to 5.5V at up to 2A. It also offers adjustable current limit and fast transient response.

The TPS40060PWPR also comes with built-in protection features, including input overvoltage, output overvoltage, neutral-point voltage clamping, and output short-circuit protection. It also offers true over-temperature protection and undervoltage lockout. The chip has an adjustable oscillator frequency of up to 1MHz, ensuring low-noise operation in both continuous and pulse-skipping modes.

The main features of the TPS40060PWPR are a high-efficiency synchronous buck architecture, wide programmable output voltage range, rich protection features, adjustable current limit, and low-noise operation. All of these features make the TPS40060PWPR suitable for a variety of applications, including LED lighting, battery chargers, point-of-load DC/DC converters, PC-card power supplies, and portable medical instruments.

The working principle of the TPS40060PWPR is that it provides a synchronous buck architecture in which it can step-down, step-up, or buck-boost the voltage from the input power source. It does this by controlling the duty cycle of an internal switch in order to achieve the desired output voltage. By sensing the output voltage, it can maintain an almost perfect voltage regulation.

The TPS40060PWPR requires two external components to operate, the power MOSFET and the Schottky diode. The MOSFET gate is driven by the TPS40060PWPR, while the Schottky diode provides current to the output. When power is applied to the input of the TPS40060PWPR, the internal switch is turned on and current flows through the Schottky diode, providing power to the output. When the current sense is reached, the TPS40060PWPR will turn off the switch and the current will be diverted away.

The TPS40060PWPR is a versatile chip that is suitable for a variety of DC/DC switching applications. It is capable of providing high efficiency and low-noise operation in a wide range of step-up, step-down, and buck-boost topologies. This chip is perfect for low-power applications that require adjustable output voltages, such as battery chargers, LED lighting systems, and portable medical instruments. It can maintain an almost perfect voltage regulation even in harsh environments.
