PRODUCTION DATA. TPS61087-Q1 SLVSB50B – DECEMBER 2011 – REVISED JUNE 2016 TPS61087-Q1 650-kHz or 1.2-MHz, 18.5-V Step-Up DC-DC Converter With 3.2-A Switch 1 1 Features 1 • Qualified for Automotive Applications • 2.5-V to 6-V Input Voltage Range • 18.5-V Boost Converter With 3.2-A Switch Current • 650-kHz or 1.2-MHz Selectable Switching Frequency • Adjustable Soft Start • Thermal Shutdown • Undervoltage Lockout • 10-Pin VQFN Package with Wettable Flanks 2 Applications • Automotive Infotainment Clusters – Instrument Clusters, Head Units – Radio, Navigation – Audio Amplifiers • Automotive Body Electronics – Body Control Modules – Gateway • Telemetrics and eCall • Advanced Driver Assistance System (ADAS) 3 Description The TPS61087-Q1 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 MHz allows 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 start-up.
