The adjustable output, set by an external resistor divider, spans 0.6V to 4.5V, so the same BOM position serves 1.2V core, 1.8V I/O, 2.5V analog, or 3.3V peripheral rails. ## Switching frequency and inductor selection Because the part lacks a synchronous rectifier, the freewheeling diode is external — a Schottky with a forward rating matching the 2A output and a reverse voltage above 5.5V is needed; the diode's forward drop adds to the total conduction loss, so the efficiency peak sits around 1-1.5A rather than at full load.","metaTitle":"Texas Instruments LM2832YMY/NOPB Buck Reg, 2A, 8-HVSSOP","metaDescription":"Texas Instruments LM2832YMY/NOPB step-down buck regulator, 2A output, 550kHz, adjustable 0.6-4.5V, -40 to 125°C.
