3.3V fixed output, 2A continuous, automotive-rated buck
The Texas Instruments TPS6209733QWRGTRQ1 is a synchronous step-down buck converter that delivers a fixed 3.3V output at up to 2A continuous from an input range of 2.5V to 6V. It belongs to the Automotive, AEC-Q100 qualified series and uses TI's iDCS-Control topology, which combines DCS-Control and forced-PWM modes for fast transient response and low output ripple across the load range.
Junction temp range and switching frequency — thermal and board-area trade-offs
The 1.5MHz to 2.5MHz switching frequency lets the design use a small 1µH to 2.2µH inductor and 10µF to 22µF output capacitor, shrinking the overall power-stage footprint on a 4-layer board.
Wettable-flank QFN — AOI-visible solder joints for automotive assembly
The 16-VFQFN package with wettable flanks (3x3mm body, exposed thermal pad) allows automated optical inspection of the side solder fillets after reflow. This is a standard requirement for automotive Tier-1 manufacturing lines — the fillet wicking up the flank confirms a reliable solder joint that a standard QFN's hidden terminations cannot provide. The surface-mount wettable-flank package mates with the 16-VQFN (3x3) supplier device footprint.
