The 2 MHz switching frequency lets you keep the inductor small — a 10 µH part in a 1210 or 2012 footprint typically works — while the 10-DSBGA package (0.4 mm pitch, 0.8 × 1.2 mm body) fits into tight power stages on multi-layer boards. Output is adjustable from a 2.5 V minimum up to 35 V using a simple resistor divider. The part lacks a synchronous rectifier, so you need an external Schottky diode — the added BOM cost is offset by the small package and no bootstrap cap. ## Temperature grade and reflow planning The 10-DSBGA package is lead-free compatible — the NOPB suffix confirms RoHS3 compliance — but check the moisture sensitivity level (MSL) before the reflow profile. A typical WFBGA this size runs MSL 1 or 2, but the reel label is the binding source. The 10-WFBGA case uses a 0.4 mm ball pitch. The board-side pad diameter should be 0.25 mm with a 0.3 mm solder-mask opening to keep the solder joint consistent across the array. Stencil thickness of 100 µm (4 mil) is the starting point; adjust aperture size if the paste volume pulls the package into tombstoning. ## Active lifecycle — sourcing posture The 10-DSBGA package is the same physical part in both supply formats.","metaTitle":"Texas Instruments LM34919TL/NOPB Buck Regulator, 600 mA","metaDescription":"Active-production TI LM34919TL/NOPB step-down buck regulator, 600 mA output, 2 MHz switching, 10-DSBGA package.
