The 1.3 MHz switching frequency lets the designer use a small inductor and ceramic output capacitor — the typical footprint fits a 10 mm² board area. But note: this is a non-synchronous buck, so an external Schottky catch diode is required. The diode's forward drop and reverse leakage add to the thermal budget, especially at high input voltage and low duty cycle. ## 10-WSON package — layout and thermal notes The 10-WFDFN (3x3 mm) with exposed pad requires a thermal land on the PCB. The datasheet's recommended footprint calls for a 2.2x2.2 mm pad with thermal vias to the inner ground layer.","metaTitle":"LM34914SD/NOPB TI Buck Regulator, 1.25 A, 10-WSON","metaDescription":"Active LM34914SD/NOPB step-down regulator from TI: 8-40 V input, 1.25 A output, 1.3 MHz switching, 10-WSON package.
