3 Description

The TLV61048 is a non-synchronous boost converter that provides a power-supply solution for products powered by a low-voltage supercapacitor and a single-cell Li-ion battery. The TLV61048 integrates a power switch with 4.7-A typical current limit to extend the discharge capability of the input source without sacrificing maximal load delivery. TLV61048 also allows the use of smaller, wide-range external inductor and output capacitor to ease design efforts. The TLV61048 operates with a selectable switching frequency of 600 kHz or 1 MHz by configuring the FREQ pin. 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 3-mm × 3-mm 6-pin SOT-23 package.
