The TPS61256CYFFT is a synchronous rectified step-down converter with integrated FETs from Texas Instruments. It is suitable for use in applications such as portable equipment, including general consumer products, computing and communication equipment, and automotive devices. The device integrates one synchronous rectified buck regulator with frequency folding technology, which allows high-accuracy, low-ripple power delivery in a small footprint. Additionally, the device incorporates Low Quiescent Current (IQ) mode and Active Burst Mode (ABM).

Designed to enable small current and high efficiency in the load line, the TPS61256CYFFT is an ideal component for applications where time- and energy-efficiency is a priority. With the integrated low-output impedance (RDS(on)), it is also suitable for applications requiring fast transient response and accurate control.

The TPS61256CYFFT has an adjustable output voltage range from 0.40V to 3.63V and is capable of delivering up to 1.5A continuous current output. With an input voltage range from 4.5V to 6V, it is highly adaptive to different operating conditions, offering enhanced user experience.

The device supports two operation modes: Burst Mode (BM) and Continuous Conduction Mode (CCM). In BM mode, the voltage regulator is enabled in bursts and the quiescent current is reduced. This mode delivers superior efficiency when light load current is requested. In CCM, the device delivers high efficiency that is ideal for typical load conditions.

The TPS61256CYFFT is available in a 10-pin Thin Small Outline Package (TSOP) form factor. It is rated to operate over a wide temperature range of -40°C to +85°C. With a robust design and various protections such as over-voltage protection, short-circuit protection, under-voltage protection, upper and lower-limit cycle-by-cycle current protection, and over-temperature protection, the TPS61256CYFFT is an ideal choice for applications requiring safe and intelligent power delivery.

The TPS61256CYFFT features frequency folding technology, which enables high-accuracy, low-ripple power delivery to the load in a small footprint. The device offers excellent transient response with low output impedance (RDS(on)), and allows for stable operations over a wide range of input voltages and load conditions. Additionally, the device incorporates integrated low quiescent current (IQ) mode and Active Burst Mode (ABM), allowing it to dynamically adjust current consumption, ensuring improved efficiency while reducing heat generation.

In summary, the TPS61256CYFFT is an ideal solution for applications requiring a simplified yet robust and efficient voltage regulator, such as consumer electronics, computing, communication and automotive devices. The device integrates various protection features, supports low-power mode, and offers a wide input voltage range, enabling it to handle diverse operating and load conditions. The frequency folding technology further enables high-accuracy and low-ripple power delivery in a small footprint.
