概述

Description

The LTC1682CMS8-5 is a dual switching regulator from Linear Technology (Analog Devices) packaged in an 8-pin CMS8 package. It provides two buck regulator channels from a common input, enabling compact dual-rail power for microprocessors, peripherals, and other mixed-signal ASICs.
Key points:
- Two buck/converter channels with externally adjustable outputs (via feedback resistors)
- Fixed-frequency PWM control with built-in protection features
- Overcurrent/short-circuit protection, undervoltage lockout, and thermal shutdown
- Soft-start and a Power-Good indicator for each channel (as described in the datasheet)
- Suitable for compact, low-profile, mixed-signal or battery-powered applications
Typical uses include portable electronics, embedded systems, and other applications requiring dual low-noise power rails in a small footprint.
For exact electrical specs (input range, output voltages, load, switching frequency) and pinout, refer to the LTC1682 datasheet.

Features

Here are the typical features of the LTC1682CMS8-5 (fixed 5V version) in an 8-pin CMS/MSOP package:
- Fixed 5V output (no external feedback network required)
- 8-pin CMS/MSOP package
- Fixed-frequency, peak-current (current-mode) switching regulator
- Internal reference and soft-start
- Enable/disable control
- Overcurrent/short-circuit protection
- Thermal shutdown protection
- Undervoltage lockout
- Wide input voltage range (suitable for portable applications)
- External components: inductor, diode (as required by the topology)
Note: For exact specifications (input range, switching frequency, quiescent current, protection thresholds), please consult the official LTC1682CMS8-5 datasheet.

Package

It uses an 8-lead MSOP package (MSOP-8).

Pinout

- Pin count: 8 pins (CMS8 package, MSOP-8 style)
- Function: Buck switching regulator controller IC (DC-DC converter control; typically requires external MOSFETs).

Manufacturer

Manufacturer: Analog Devices, Inc. (owner of Linear Technology; LTC parts carry the Linear Technology heritage).
What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.
