Product details

Buck-boost regulator for mixed-rail designs

The LTC3130IUDC-1#PBF is a single-inductor buck-boost switching regulator from Analog Devices that delivers a programmable output at up to 600 mA. Synchronous rectification keeps efficiency high without an external Schottky diode. The 1.2 MHz switching frequency lets you use small inductors and ceramics, shrinking the total solution footprint.

Output voltage selection and thermal design

The output is programmable via pin-strapping to one of four fixed voltages: 1.8 V, 3.3 V, 5 V, or 12 V. That saves a feedback divider and lets you change rails without a resistor spin. The 20-QFN package (3x4 mm) with exposed pad needs a good thermal via stitch under the paddle — at 600 mA continuous output from a low input, the junction can rise quickly.

It is ROHS3 compliant. No LTB risk or NRND flag applies.

Frequently asked questions

How does LTC3130IUDC-1#PBF compare to LTC3129?

The LTC3129 is a lower-power sibling with a 200 mA output rating, while the LTC3130IUDC-1#PBF delivers up to 600 mA. Both share the same buck-boost topology and wide input range, but the LTC3130 is the choice when the load exceeds 200 mA.

What is the typical efficiency of LTC3130IUDC-1#PBF?

Efficiency depends on input-to-output voltage ratio and load current. The datasheet provides typical curves; expect peak efficiency above 90% for moderate step-up/step-down ratios near 600 mA output. No single efficiency figure is listed in the summary specs.
