Product details

Multi-topology controller in a small footprint

The LTC1772BES6#TRPBF is a current-mode switching regulator controller supporting step-up, step-down, and step-up/step-down topologies — buck, boost, and flyback. It drives an external N-channel MOSFET with a fixed 550 kHz switching frequency. The supply range is 2.5 V to 9.8 V on Vcc. The TSOT-23-6 package operates from -40°C to 85°C.

Supply voltage range and output configuration

The Vcc range is 2.5 V to 9.8 V. Output configuration is positive, single phase, with a maximum duty cycle of 100%. No synchronous rectifier.

Lifecycle and sourcing posture

The LTC1772BES6#TRPBF is listed as Active with ROHS3 compliance. For BOM planning, the active status means no immediate supply risk from end-of-life.

Frequently asked questions

What topologies does LTC1772BES6#TRPBF support?

It supports step-up, step-down, and step-up/step-down topologies — specifically buck, boost, and flyback configurations.

What package does LTC1772BES6#TRPBF come in?

It comes in a TSOT-23-6 package (SOT-23-6 Thin), surface-mount only.

What is the equivalent of LTC1772BES6#TRPBF?

The closest functional peer is LTC1772BIS6#TRMPBF, which shares the same topology support, switching frequency, and supply range, differing only in the tape-and-reel suffix. For a buck-only controller with soft start, consider LTC1771ES8#TRPBF.
