Product details

Buck-boost regulator for wide-input-rail designs

The LTC3115IDHD-1#TRPBF: Step-up/step-down (buck-boost) switching regulator with adjustable output from a 2.2 V to 40 V input supply. Integrates synchronous rectification and provides 1 A continuous output current with 2 A switch current limit.

1 A / 2 A output — what it means for the load budget

The 1 A output rating is the continuous load the regulator can hold in regulation across the full input range; the 2 A figure is the peak switch current limit. Junction temperature range is -40°C to 125°C.

Switching frequency — inductor sizing vs efficiency trade-off

Switching frequency is programmable from 100 kHz to 2 MHz via an external resistor. Input voltage range is 2.2 V to 40 V.

Active production — no LTB risk for new designs

Active product status and ROHS3 compliant. No last-time-buy notice or obsolescence PCN announced. Output current is 1 A.

Frequently asked questions

What is the output current capability of LTC3115IDHD-1#TRPBF?

The LTC3115IDHD-1#TRPBF delivers a continuous output current of 1 A, with a 2 A peak switch current limit on the input side. The 1 A rating is the maximum load the regulator can sustain in regulation across the input voltage range.

Does LTC3115IDHD-1#TRPBF require any external components?

Yes, like any switching regulator, it requires external inductors, input/output capacitors, and feedback resistors to set the output voltage. The switching frequency is set by an external resistor. The datasheet provides typical application circuits.
