TPS61087-Q1 Datasheet | Texas Instruments

Features - 1 Qualified for automotive applications - Functional Safety-Capable - Documentation available to aid functional safety system design - 2.5-V to 6-V Input voltage range - 18.5-V Boost converter with 3.2-A switch current - 650-k Hz 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 e Call - Advanced driver assistance system (ADAS) 3 Description The TPS61087-Q1 is a high-frequency, highefficiency DC-to-DC converter with an integrated 3.2‑A, 0.13-Ω power switch that is capable of providing an output voltage up to 18.5 V. The selectable frequency of 650 k Hz or 1.2 MHz allows the use of small external inductors and capacitors, and provides fast transient response. The external pensation allows optimizing the application for specific conditions. A capacitor connected to the softstart pin minimizes inrush current at start-up.
