3 Description

The TPS61087 is a high-frequency, high-efficiency

DC-DC converter with an integrated 3.2-A, 0.13-Ω

power switch capable of providing an output voltage

up to 18.5 V. The selectable frequency of 650 kHz or

1.2 MHz allows the use of small external inductors

and capacitors and provides fast transient response.

The external compensation allows optimization of the

application for specific conditions. A capacitor

connected to the soft-start pin minimizes inrush

current at startup.
