The TPS61100PW is a versatile step-up DC/DC converter designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This high-performance power management integrated circuit is specifically tailored to meet the needs of battery-powered and low-power applications.

With an input voltage range of 1.8V to 5.5V, the TPS61100PW is perfectly suited to operate from a variety of energy sources, including single-cell Li-Ion batteries, multiple Alkaline/NiCd/NiMH cells, or regulated 3.3V and 5V power supplies. This flexibility makes the device ideal for portable electronics, such as handheld devices, medical equipment, and wireless communication systems.

The TPS61100PW boasts a fixed-frequency pulse-width modulation (PWM) mode that ensures efficient operation at moderate to high load conditions, while its power-save mode enhances efficiency at light loads. This dual-mode operation helps to extend battery life in portable applications, making it an energy-efficient choice for designers.

Outfitted with a 2A switch current limit, the TPS61100PW can deliver output voltages as high as 28V, which is particularly beneficial for driving white LEDs used in backlighting applications. Additionally, the device features a low shutdown current of less than 1µA, further conserving battery life when the device is not in active use.

For protection and reliability, the TPS61100PW includes over-temperature and over-current protection. It also offers a programmable under-voltage lockout and a soft-start feature that minimizes inrush current during startup, contributing to the stability and longevity of the end application.

The TPS61100PW comes in a 16-pin TSSOP (Thin Shrink Small Outline Package) that is RoHS compliant and designed for space-saving in PCB layouts. Its thermal performance is enhanced by a thermal pad that allows for efficient heat dissipation.

Overall, the TPS61100PW from Texas Instruments is a comprehensive solution for power conversion that combines efficiency, flexibility, and protection in a compact package, making it an excellent choice for designers seeking to optimize their power management strategy in portable and low-power electronics.
