Product details

Step-up converter for portable and multi-rail designs

Two selectable switching frequencies — 600 kHz and 1.2 MHz — let the designer trade inductor size against switching losses and EMI; the higher frequency shrinks the inductor footprint but increases gate-drive losses and may push the fundamental switching harmonic above the AM band.

Input and output voltage envelope

Output can be set from 2.5 V minimum up to 27 V maximum via an external resistor divider.

The non-synchronous rectifier topology (no internal synchronous FET) means an external Schottky diode is required for the boost stage; the diode forward voltage and thermal rating must be factored into the efficiency and layout.

Frequently asked questions

What is the output current capability of TPS61080DRCT?

The internal switch is rated for 500 mA. The actual output current at the boosted voltage depends on the input-to-output ratio and efficiency — a 5 V to 12 V conversion at 200 mA is typical, but the switch current limit must be respected in the load budget.
