TPS62672YFDR is a high quality, high efficiency, DC-DC switch-mode power-supply for mobile applications. It provides up to 5A output current and features a variety of features including low quiescent current and very fast transient response. It also offers a wide input voltage range from 2.5 to 5.5 V, adjustable soft-start time and selectable operation as a buck, boost or buck-boost regulator. This makes it ideal for powering devices such as digital cameras, smart phones and tablets.

The general application field for TPS62672YFDR is consumer and mobile electronics, such as portable medical and handheld industrial or consumer applications. It is designed to drive the LCD display and backlight in consumer electronic products. This regulator can also be used in automotive, telecommunication, and printer applications.

The working principle of the TPS62672YFDR is very simple and straightforward. Its core is a switch-mode power-supply based on a synchronous waveform generator operating in a pulse width modulation (PWM) mode. In PWM mode, the average output voltage is controlled by adjusting the duty-cycle of the waveform generator. This waveform is used to drive a MOSFET transistor. In switch-mode-power-supplies, the output voltage is kept within a very narrow range by varying the on/off times of the MOSFET. The TPS62672YFDR controls the MOSFET’s conduction time and time-off by a feedback path from an internal voltage error amplifier connected to a voltage reference. The voltage reference keeps a steady output voltage, and the feedback path takes care of any variations of the output voltage.

The TPS62672YFDR is equipped with a wide variety of features such as: an adjustable soft-start time, a low quiescent current, a very fast transient response, a wide input voltage range, the ability to support battery-powered applications, the ability to operate as a buck, boost, or buck-boost regulator, and Over Voltage Protection. Its low quiescent current helps improve device efficiency while reducing the overall power consumption, and its very fast transient response allows the regulator to quickly and accurately respond to load current changes. Additionally, the TPS62672YFDR’s Over Voltage Protection ensures that the regulated output voltage remains within its specified operating range even under fault conditions.

The TPS62672YFDR is a compatible replacement for legacy switching regulators, such as the LM317, and provides adjustable output voltage up to 5.5 V. It is capable of output current up to 5A and has a wide range of features including input Voltage Range from 2.5 to 5.5V, soft-start time and selectable operation as a buck, boost, or buck-boost regulator. The TPS62672YFDR helps reduce power consumption, increases efficiency and allows for highly accurate voltage regulation over a wide temperature range and varying load conditions.
