The TPS63051YFFT is a boost-mode DC-DC switching regulator IC from Texas Instruments, which is used to convert an input voltage to a higher output voltage with a high level of efficiency. This voltage regulator is housed in a compact 16-pin PowerPAD™ package and is designed to meet the most stringent requirements for performance and power density.

This DC-DC converter IC is optimized for small form factor applications and includes a wide input range, adjustable output voltage, low quiescent current, excellent output voltage accuracy and current limit protection. It is available in an ultra-thin PowerPAD package that reduces solution size, simplifies the layout, and enhances the overall system performance.

The TPS63051YFFT is ideal for battery-powered products that require high efficiency conversion with a maximized battery life. Such products include portable consumer electronics, including digital cameras, digital audio recorders and players, music Keyboards and other handheld digital devices. The wide input capability extends the efficiency of the converter across a large input voltage range, allowing the converter to be powered directly from the battery.

The integrated adjustable current limit and over-temperature protection make this DC-DC converter easy to optimize for different battery pack and safe operation conditions. The adjustable output voltage control can be used to set the output voltage in either the power or noise-sensitive applications.

In terms of its working principle, the TPS63051YFFT utilizes an internal high-side NMOS power switch, inductor and energy storage component to create an energy path from the input to the output. The input voltage is converted to a higher output voltage through a boost-mode switching process whereby the inductor current is caused to ramp up, storing energy in the inductor. This stored energy is then transferred to the output through the power switch, resulting in a higher output voltage.

The TPS63051YFFT uses a pulse-width modulation (PWM) control that helps achieve better efficiency over a wide load range. This switching regulator also has a programmable frequency and hysteretic control mode for various load conditions, enabling it to inherently manage load transients and maximize efficiency. The built-in Lead Acid Battery (LAB) and Lithium-ion battery (Li-ion) discharge profiles make it ideal for use in applications such as shared system power management and battery backed-up systems.

The TPS63051YFFT is an ideal choice for systems requiring high power density and superior power management capabilities, with its ability to support a wide input range, adjustable output voltage and low quiescent current. The integrated features of this DC-DC converter, such as current limit protection, adjustable frequency and over-temperature protection, make it easy to optimize for different battery pack and safe operation conditions. This switching regulator is an ideal solution for applications that require efficient and reliable power conversion, such as portable consumer electronics, music keyboards, and other handheld digital devices.
