650 kHz/1.2 MHz, 18.5 V STEP-UP DC-DC CONVERTER WITH 3.2A SWITCH

Overview

TopologyBoost Converter
Input voltage5 V
Switching frequency650-1200 kHz
Output 115 V / 0.9 A
IC revisionD

Description

The TPS61087 is a high frequency, high efficiency DC to 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 MHzallows the use of small external inductors and capacitors and provides fast transient response. The external compensation allows optimizing the application for specific conditions. A capacitor connected to the soft-start pin minimizes inrush current at startup.
