Overview

Description

LT1640HCS8 is an 8‑pin variant of Linear Technology’s LT1640 switching regulator (DC‑DC converter) in an HCS8 package. It’s designed for high‑efficiency generation of a regulated output from a higher input, using external components (inductor, diode, input/output capacitors). The device implements current‑mode control and includes protections such as current limit, thermal shutdown, and overvoltage, with an enable input for easy sequencing. The HCS8 suffix denotes the 8‑lead HCS8 package suitable for surface‑mount assembly. Typical applications include point‑of‑load supplies, battery-powered and automotive electronics. For exact specs (input range, switching frequency, max output current, efficiency), consult the LT1640 data sheet and package variant documentation.

Package

LT1640HCS8 uses an 8-pin SO-8 (Small Outline) package.

Pinout

- Pin count: 8 pins (HCS8 package)
- Function: LT1640HCS8 is a single-supply, high-speed, general-purpose op-amp in an 8-pin package.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). The LT1640 originated from Linear Technology, which ADI acquired in 2017.
What kind of company: ADI is a global American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs for automotive, communications, industrial, and consumer markets.

Application

LT1640HCS8 is a high-efficiency buck switching regulator in an 8-pin package. Typical applications:
- Battery-powered systems needing a regulated lower rail
- Portable electronics and microcontroller/DSP power supplies
- Automotive and industrial equipment rails
- Post-regulators for LCDs, sensors, and RF front-ends
- Space-constrained, low-noise DC-DC conversion in telecom/industrial gear
