Product details

Boost converter with 3.2 A switch and dual-frequency choice

The TPS61087DRCR is a Texas Instruments boost regulator that steps up from a 2.5 V to 6 V input rail to an adjustable output up to 18.5 V. The switching frequency is pin-selectable between 650 kHz and 1.2 MHz.

Sourcing and lifecycle: active production, no direct second-source

The LM2750LD-ADJ/NOPB is a charge-pump step-up with only 120 mA output — not a functional replacement for a 3.2 A boost converter. The LMR33630APCQRNXRQ1 and LMS3655MQURNLRQ1 are step-down (buck) regulators, not boost, so they are not drop-in alternatives. The part is supplied in tape-and-reel (TR) or cut-tape (CT) options per the BOM quantity. No stock-holding claim is made; we source per RFQ.

Frequently asked questions

What is the output current rating of TPS61087DRCR?

The internal switch is rated for 3.2 A continuous. The actual output current depends on the input-to-output voltage ratio and efficiency — at 5 V in, 12 V out, expect roughly 1 A to 1.2 A output before the switch current limit is reached.

Is the LM2750LD-ADJ/NOPB a replacement for TPS61087DRCR?

No. The LM2750 is a charge-pump step-up with a 120 mA output — it cannot deliver the 3.2 A switch current of the TPS61087. The TPS61087 is a true inductor-based boost converter; the LM2750 is a switched-capacitor part with much lower output capability.
