TLV61048

The TLV61048 is a non-synchronous boost converter that 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 could be configured at 600 kHz for higher efficiency. At the light load, the device enters into the PFM operation to achieve higher efficiency. Other key features of this device include:

  • Internal Compensation
  • Internal 2-ms soft-start time
  • 1-uA shutdown current
  • Thermal shutdown protection
  • 2.9-mm × 1.6mm 6-pin SOT-23 package
