Each of the four outputs delivers either 400 mA or 600 mA, with the higher-current channel typically assigned to the core rail and the lower-current channels to I/O or auxiliary supplies. The 2.25 MHz switching frequency keeps the inductor values around 1 µH to 2.2 µH, which saves board area in space-constrained portable and battery-powered designs. Each output is adjustable down to 0.425 V and up to 3.78 V, which spans the common core voltages for FPGAs, SoCs, and low-voltage digital logic as well as 1.8 V, 2.5 V, and 3.3 V I/O rails. The synchronous rectifier eliminates the external Schottky diode, improving efficiency at moderate load currents. The part ships in Tube form. The ROHS3 compliance is consistent with current lead-free assembly requirements; no special handling beyond standard MSL precautions is called out in the listing. ## Output voltage flexibility for multi-rail designs The output is adjustable and programmable. The minimum output voltage is 0.425 V, and the maximum is 3.78 V. This means a single LTC3562 can generate a 1.0 V core rail, a 1.8 V DDR termination rail, a 2.5 V analog rail, and a 3.3 V I/O rail from one input supply. The 0.425 V floor is low enough for the latest deep-submicron FPGA cores that run at 0.9 V or 0.85 V, though the 400 mA per-channel limit means the designer must budget the current draw before assigning rails. ## Active lifecycle — no near-term EOL risk Buyers should qualify the part for new designs with the usual PCN monitoring in place.","metaTitle":"LTC3562EUD#PBF Quad Buck Regulator, 2.25 MHz, 400mA/600mA","metaDescription":"LTC3562EUD#PBF quad step-down regulator from Analog Devices. 2.7V to 5.5V input, 4 outputs up to 600mA, 2.25MHz switching.

The output voltage range is 0.425 V to 3.78 V, so a 1.2 V rail is well within the adjustable range. The actual set point is programmed via the feedback resistor divider or, for the programmable variant, through the serial interface."},{"question":"What are the equivalents or alternatives for LTC3562EUD#PBF?","answer":"The closest functional peer from the same manufacturer is the LT3640EFE#PBF, a dual-output buck regulator with a 2 MHz switching frequency and a 1.1 A per-channel output, but it has only two outputs and a 125°C junction temperature rating. For a quad-output replacement, the LT3509IMSE#PBF offers two outputs at 700 mA, not four.
