TPS63011YFFT is an advanced, voltage-mode, non-synchronous, boost regulator with an integrated power switch designed to power high-performance microprocessors and other applications. This DC/DC converter can deliver up to 3 A of output current and its wide input voltage range makes it the ideal solution for various automated industrial and consumer systems. This single-chip solution simplifies system design and minimizes board space.

TPS63011YFFT is designed to operate in a voltage-mode control system. It dynamically adjusts its switching frequency relative to the output load and input voltage, providing superior transient load response. The integrated power switch can be configured to operate in either synchronous or non-synchronous mode, providing the power supply designer with the flexibility to optimize for efficiency or size. The on-chip loop compensation integrates an external compensation network, providing cost savings in components and board space.

TPS63011YFFT includes an internal 0.25A, 500V logical power-on reset circuit and an internal 3.3V LDO, allowing for independent supply of the logic and switching blocks. The regulator also includes an optional shutdown mode, allowing the designer to power down the system as needed. The regulator also features pulse-skipping operation, providing a way to further reduce the output current ripple during light-load conditions.

The TPS63011YFFT is ideal for a variety of applications, including Point-of-Load (POL) converters, white goods, industrial automation, and consumer appliances. The device is available in a 4x4 LTQFP package and supports an input voltage range of 5.5V to 20V and an output voltage range of 0.82V to 14V. The integrated PWM controller can operate up to a 2.2MHz switching frequency and provides up to 93% efficiency. The device also provides protection against open and shorted outputs as well as over-temperature conditions.

The TPS63011YFFT operates as a boost converter, switching between its two output states in order to maintain the desired output voltage. The switching frequency is determined by the input voltage and output current. It uses pulse-width modulation (PWM) to switch its output state, resulting in the charging and discharging of its power capacitor at a rate determined by the PWM input signal. The output voltage is regulated by monitoring the voltage on the power capacitor via an internal error amplifier.

In summary, the TPS63011YFFT is an advanced, voltage-mode, non-synchronous, boost regulator ideal for a wide range of applications due to its wide input voltage range, high output current, and high efficiency. The on-chip protections and loop-compensation features of the device make it a reliable, low-cost solution for various automated industrial and consumer systems.
