General Description

The TS1910 is a high performance, high efficiency step up DC-DC Converter with integrated 2A. The TS1910

converter input voltage ranging from 2.6 to 5.5V. The Output voltage can be set up to 27V. The selectable

frequency of 680kHz and 1.2MHz allows the use of small external inductors and capacitors and provides fast

transient response. Current mode control with external compensation network makes it easy to stabilize the

system and keep maximum flexibility. Programmable soft start function minimizes impact on the input power

system. Internal power MOSFET with very low R_DS(ON)provides high efficiency. The TS1910 automatically transits

from PWM to PFM during light load condition further increasing efficiency. The converter also provides protection

functions such as Current Limit and Thermal shutdown.
