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.
