概述

Description

LT1076CR is a Linear Technology (now Analog Devices) buck switching regulator IC. It’s a high‑efficiency, monolithic controller with an internal power switch used to convert a higher DC input to a lower, regulated output.
Key points:
- Buck regulator architecture: requires external components (inductor, Schottky diode, input/output capacitors, and a feedback network) to set the output.
- Features typically include current‑mode control, overcurrent/overtemperature protection, and good transient response.
- Output voltage is set by a feedback divider; device is suitable for point‑of‑load and other DC‑DC applications.
- CR suffix denotes the package/temperature/lead‑frame variant (e.g., commercial temperature range in a specific package).
Common use:
- DC‑DC power supplies for embedded systems, battery-powered gear, telecom, and other applications needing efficient voltage conversion.
Note:
- For exact electrical specs (input range, output options, switching frequency, pinout), refer to the LT1076CR datasheet.

Features

LT1076CR is a 5A, high-voltage, step-down switching regulator. Key features include:
- Wide input range up to about 60V
- Adjustable output via external resistor divider (feedback control)
- Internal 5A switch with current-mode PWM
- Fixed-frequency operation (typical ~100 kHz)
- Protection: cycle-by-cycle current limit, overtemperature shutdown
- Enable/shutdown input forLatch-free shutoff
- Soft-start and minimal external components for regulation
- Requires external components: inductor, Schottky catch diode, input/output capacitors
- Packaging: CR suffix denotes RoHS/compliant 8-pin package (DIP/SO-8 variants)
Note: external components and layout are required for proper operation.

Package

LT1076CR is in an 8-pin plastic DIP (DIP-8) package.

Pinout

- Pin count: 8 pins (SO-8/DIP-8)
- Function: High-voltage switching regulator controller with an internal switch; used to implement switch-mode power supplies (buck/boost/inverting topologies) with external inductor, diode, and output components. Includes reference, error amplifier, oscillator, current limit, and shutdown.

Manufacturer

Analog Devices (the LT1076 originated with Linear Technology; Linear Technology was acquired by Analog Devices in 2017).
Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits.

Application

LT1076CR is a 60V, 3A switching regulator capable of buck, boost and inverting topologies. Applications: automotive and industrial DC-DC converters, high-voltage pre-regulators, battery-powered power supplies, auxiliary rails for microprocessors/telecom, and LED driver/topology circuits using a wide input range.
