It accepts a wide input range from 2.9 V to 38 V and delivers a positive, isolation-capable output configurable up to 38 V. The switching frequency is programmable from 94 kHz to 2.55 MHz, letting you trade efficiency against inductor size. This part is qualified for automotive under-hood and industrial environments with an operating temperature range of -40°C to 125°C. It comes in a 16-pin WQFN (3x3 mm) package with an exposed pad for thermal management. ## Switching frequency and compensation The switching frequency range of 94 kHz to 2.55 MHz is set with a single resistor. Lower frequencies reduce switching losses but require larger inductors; higher frequencies shrink the magnetics but increase FET and diode losses. The part uses current-mode control with external compensation — you'll need to select the compensation network (RC) based on the output capacitor and inductor values. The datasheet application circuits cover typical automotive boost and SEPIC topologies.","metaTitle":"TPS55340QRTETQ1 Automotive Boost Converter, 5.25 A Switch","metaDescription":"TI TPS55340QRTETQ1 automotive AEC-Q100 boost converter, 2.9-38V input, 5.25A switch, adjustable output, active production.
