Buck-boost regulator for unregulated input rails
The LTC3130IUDC#PBF is a single-output, adjustable buck-boost switching regulator from Analog Devices. It accepts an input from 2.4 V to 25 V and delivers up to 600 mA at an adjustable output from 1 V to 25 V. The 1.2 MHz fixed switching frequency keeps external inductor and capacitor values small.
What the 2.4 V to 25 V input range means on the bench
The 2.4 V minimum and 25 V maximum define the input range. The 600 mA output suits small loads.
It lives in a 20-lead QFN with an exposed pad, 3 mm by 4 mm. That pad needs a good thermal via pattern under it — the scorch mark on a dead board often traces back to a regulator that lifted its own pad because the ground plane was starved of vias.
We source it through independent distribution and quote it to order against an RFQ.
