Description

Introduction: The LTC1760CFW#PBF is Linear Technology’s high-efficiency, current‑mode buck regulator (DC‑DC converter). The CFW suffix identifies the package variant; PBF indicates Pb‑free, RoHS‑compliant. It integrates the switch and control circuitry and requires an inductor, diode (or uses synchronous rectification), input and output capacitors, and a resistor divider to set the output voltage. Features typically include enable control, soft‑start, overcurrent and thermal protection, and a fixed switching frequency. It is used to convert a higher input voltage to a stable lower voltage for microprocessors, FPGAs, or other digital circuits in portable, industrial, or automotive power rails. For exact electrical specs, pinout, and usage notes, consult the LTC1760 datasheet and app notes. The datasheet provides recommended application circuits and layout guidelines.

Features

Here are the typical features of the LTC1760CFW#PBF family (compact buck regulator):
- High-efficiency step-down DC/DC converter in an 8-pin package
- Input voltage range: up to about 5.5 V
- Output: adjustable via external resistor network; fixed-output variants available
- Switching frequency: on the order of a few MHz (typical around 2 MHz)
- Internal current-mode PWM for fast transient response
- Enable/shutdown control pin
- Soft-start to limit inrush and reduce output overshoot
- Overcurrent (short-circuit) protection and thermal shutdown
- Stable with ceramic output capacitors
- Low quiescent current; suitable for battery-powered apps
- Pb-free (PBF) package option
Note: exact electrical values (input range, output options, efficiency, current capability) vary by variant. Please consult the LTC1760CFW#PBF datasheet for precise specs.

Package

MSOP-8 (8-pin, 3×3 mm) package. The PBF suffix indicates Pb-free/RoHS-compliant.

Pinout

8 pins. It is a buck (step-down) switching regulator with an internal high‑side switch. It converts a higher input voltage to a lower regulated output using an external inductor and Schottky diode (and feedback network). The package provides typical regulator pins such as VIN, GND, LX/SW (switch node), FB (feedback), EN (enable), BYP (bypass), RT (frequency select), etc. In short: 8‑pin buck converter IC.

Manufacturer

Manufacturer: Analog Devices, Inc. (the LTC prefix comes from Linear Technology, which Analog Devices acquired in 2017).
What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits for industries such as aerospace, automotive, communications, consumer electronics, and industrial.

Application

Typical application areas for LTC1760CFW#PBF:
- High-efficiency, compact buck power for portable/battery-powered electronics
- Point-of-load rails for microprocessors, DSPs, and FPGAs
- Telecom and networking equipment power supplies
- Automotive and industrial control electronics
- Distributed power systems and instrumentation power rails
