LTC1760CFW#TRPBF

LTC1760CFW#TRPBF is a Linear Technology (now Analog Devices) part number for the LTC1760 DC-DC buck regulator. The “CFW” suffix identifies the specific package variant for the IC. The “#TRPBF” suffix means the device is supplied in Tape & Reel packaging and Pb-free (lead-free) per supplier packaging conventions.
What it is:
- A high-efficiency step-down switching regulator used to convert a higher input voltage to a lower regulated output.
- Requires external components (inductor, input/output capacitors, and a feedback network; a diode if the design isn’t fully synchronous).
What to use it for:
- Powering microprocessors, digital logic, or other loads from a higher voltage source with good efficiency and compact hardware.
What to check in the datasheet:
- Pinout and package details for CFW
- Electrical characteristics (input/output voltage ranges, current capability, protection features)
- Recommended external components and typical application circuits
- Packaging, lead-free and tape-and-reel information for procurement
In short: it’s a buck regulator IC variant packaged for automatic handling and Pb-free shipment.

Here are the typical features of LTC1760CFW#TRPBF (LTC1760 family):
- Buck DC-DC regulator with integrated high-side switch
- Wide input range suitable for single/low-voltage supplies (typical 2.4V–5.5V)
- Adjustable output via external resistor divider
- High efficiency with fixed-frequency current-mode operation
- Automatic light-load operation for improved efficiency
- Overcurrent protection and thermal shutdown
- Undervoltage lockout and enable/shutdown control
- Soft-start to limit inrush and overshoot
- Internal compensation (minimal external components)
- Small 8-pin package; RoHS compliant; Tape & Reel (TRPBF)
Note: exact voltage ranges, output limits, and switching frequency are specified in the datasheet.

8-pin MSOP package (MSOP-8), about 3×3 mm; Pb-free. TRPBF indicates Tape & Reel packaging with Pb-free compliance.

- Pin count: 8 pins (8-pin package)
- Function: A monolithic buck (step-down) switching regulator with an internal power switch; converts a higher input voltage to a lower regulated output using an external inductor (and diode or synchronous path); includes feedback and enable/soft-start features.

Analog Devices, Inc. (ADI). It is a global semiconductor company that designs, manufactures, and markets integrated circuits and related components. The LTC parts originated from Linear Technology, which ADI acquired in 2017.
