The TPS61175QPWPRQ1 from TI is an AEC-Q100 3A boost converter for LED driver applications with 2.9-18V input and 1.2MHz switching in HTSSOP-14 for automotive lighting.

The TPS61175QPWPRQ1 is a 3A boost converter from Texas Instruments in HTSSOP-14, AEC-Q100 qualified for automotive applications. It converts input voltages from 2.9-18V to output voltages up to 38V, making it ideal for LED backlight drivers and automotive display power. The device uses current-mode control with external compensation (COMP pin), allowing optimization for different inductor values and output capacitors. The switching frequency is programmable from 500kHz to 1.2MHz via a resistor on FSW, or can be synchronized to an external clock via the FREQ pin. The internal 3A N-channel MOSFET has 0.18 ohm RDS(on), providing low conduction loss. The soft-start (SS) pin controls output voltage ramp-up, limiting inrush current. The device features: (1) Overcurrent protection at 4.5A; (2) Overvoltage protection at 42V (protects against open-LED condition); (3) Thermal shutdown at 160C; (4) Pulse-skipping at light load for improved efficiency. The -Q1 suffix specifies AEC-Q100, automotive qualified (-40C to +125C). The -QPWPRQ1 suffix specifies HTSSOP-14, tape-and-reel. Applications include: automotive LCD backlight (8-12 series white LEDs), head-up display power, and industrial 24V-to-48V boost conversion.
