Its buck-boost topology means the output stays regulated whether the input is above, below, or equal to the output voltage — useful when the supply rail sags below the target (like a battery discharging) or surges above it. Switching at 1.2 MHz, the part uses a synchronous rectifier — the internal low-side FET replaces the external Schottky diode, which improves efficiency at light loads and shrinks the inductor footprint. The single output is positive and programmable from a 2.5 V minimum up to 15 V. Housed in a 16-lead WFQFN with exposed pad (3 mm × 3 mm), the LTC3129EUD-1#PBF is surface-mount and requires a thermal land on the PCB to pull heat from the die. The exposed pad is the primary thermal path — the datasheet layout recommendation ties it to the ground plane with multiple vias. Supplied in a tube (the listed package format), the part is also available in tape-and-reel under alternate order codes.","metaTitle":"LTC3129EUD-1#PBF Buck-Boost Regulator, 200mA, 16-QFN","metaDescription":"Analog Devices LTC3129EUD-1#PBF step-up/step-down regulator, 200mA output, 1.92-15V input, 1.2MHz switching.
