TLV61048 14 V Output-Voltage Non-Synchronous Boost Converter
Texas Instruments' converter in an SOT-23 package is ideal for industrial isolation DC/DC applications
Texas Instruments' TLV61048 is a non-synchronous boost converter that provides a power-supply solution for products powered by a low-voltage super capacitor and a single-cell Li-Ion battery. The TLV61048 integrates a power switch with 3.7 A typical current limit to extend the discharge capability of the input source without sacrificing maximal load delivery.
The TLV61048 converter can be configured at 600 kHz for higher efficiency or 1 MHz for a smaller inductor and output capacitor. At the light load, the device enters the PFM operation to achieve higher efficiency. The boost converter has built-in 2 ms soft-start to minimize the inrush current. The TLV61048 is available in a 2.9 mm x 1.6 mm 6-pin SOT-23 package.
