TPS61080 and TPS61081 High Voltage DC to DC Boost Converter - Texas Instruments

TI introduced it’s new 1.2-MHz TPS61080 and TPS61081 high-voltage DC/DC boost converter, supporting input voltages from 2.5-V to 6-V. The chips  combines a 1.3-A current switch, a power diode and I/O isolation . The chip is optimized to support single-cell Li-Ion batteries, as well as a three-cell NiMH battery pack or a USB port 5 Volts Input. It also supports point-of-load voltages, such as 3.3-V to 12-V or 5-V to 24-V. The IC integrates a power MOSFET and power diode in a 3 mm x 3 mm QFN package, providing the designer an extremely compact solution with reduced external component count. The converters switching frequency is of 1.2 MHz or 600 kHz.

>Texas introduced a highly integrated boost converter that supports 27-V of output voltage and improves battery life in portable industrial and medical applications, such as portable diagnostic systems.

The TPS61081 can survive and protect external components from a short-circuit situation on any single pin except the input voltage pin. Other protection features on the TPS61081 include programmable soft-start,  over-current protection, over-voltage protection, under-voltage lockout and thermal shutdown.

For development, TI also offers the TINA-TI 7.0 and SwitcherPro Design Tools. The SwitcherPro tool allows designers to create both internally and externally compensated DC/DC power supply designs and analyze circuit performance.
