TPS6104x-Q1 High-Frequency Boost Converters Texas Instruments TPS6104x-Q1 High-Frequency Boost Converters are ideal for automotive applications with output voltages up to 28V. The TPS6104x-Q1 operates from a pre-regulated low voltage rail, dual-cell NiMH/NiCd, or a single-cell Li-Ion battery, supporting input voltages from 1.8V to 6V. The TPS6104x-Q1 converters generate a switching frequency up to 1MHz, enabling the use of small external components such as ceramic and tantalum output capacitors. The TPS6104x-Q1 devices combined with the space-saving, 5-pin SOT-23 package achieve a small overall solution size.
