TPS61240IDRVRQ1 Synchronous Boost Converter
The TPS61240IDRVRQ1 is an AEC-Q100-qualified, 3.5 MHz fixed-frequency synchronous step-up DC-DC converter from Texas Instruments that delivers a regulated 5 V rail from a 2.3 V – 5.5 V input, supports battery currents up to 450 mA, and maintains >90 % efficiency while needing only three external components (2 × ceramic capacitor + 1 × 2.2 µH inductor) in a 2 mm × 2 mm WSON-6 package with <13 mm² total solution footprint .
TPS61240IDRVRQ1 boost converter Applications
● Automotive infotainment & cluster: post-boost 5 V rail for CAN, USB-OTG or SBC supplies that must survive cold-crank down to 2.3 V
● ADAS cameras & sensors: tiny footprint and low EMI (<13 mm²) fit behind CMOS imagers; Grade-3 (–40 °C to +85 °C) or Grade-2 (–40 °C to +105 °C) options support camera modules inside heated windshields
● Portable medical & IoT trackers: single Li-ion or two-cell alkaline boost to stable 5 V for RF PAs, biosensors or OLED displays while keeping standby drain <1 µA
● Industrial field transmitters: harvest energy from 1-cell Li-primary down to 2.3 V and deliver 5 V @ 200 mA to 4–20 mA loop electronics
● USB-OTG / battery-backup – true load disconnect prevents battery drain when the bus is powered by another source
Alternatives step-up converters
● TPS61240: pin-compatible non-automotive version with identical specs for industrial/consumer use
● TPS61241-Q1: 4.75 V fixed output, 2 A switch, same 2 × 2 mm WSON for higher current 5 V rails
● TPS61058-Q1: 2 MHz, 1.5 A switch, adjustable 3.3-12 V, suits 9 V or 12 V sensor bias from 3 V battery
● L6920DTR: STM 0.6 V start, 800 mA switch, adjustable 1.8-5.2 V, SC-74 if height is critical
