3 Description
The 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 could be configured at 600 kHz for
higher efficiency or 1 MHz for smaller inductor and
output capacitor. At the light load, the device enters
into the PFM operation to achieve higher efficiency.
The TLV61048 has built-in 2-ms soft start to minimize
the inrush current.
The TLV61048 is available in a 2.9-mm × 1.6-mm 6-
pin SOT-23 package.
