Description

LNK626PG IC – AC-DC Power Supply Switching IC

The LNK626PG IC is an integrated power supply switching component from Power Integrations’ LinkSwitch-CV family. It is designed for low-power AC-DC converter circuits that require controlled output voltage. This IC combines switching and control functions in one package, helping simplify compatible power supply designs and reduce the need for certain external control components.

The LNK626PG is used in power conversion designs where electrical energy from an AC input must be converted into a suitable DC output. Its integrated design makes it useful for electronic power supplies, adapters, standby supplies, auxiliary power circuits, and selected household or industrial electronic equipment. Actual suitability depends on the circuit design and the requirements of the equipment.

Product Overview

The LNK626PG is a power management integrated circuit intended for offline switching power supplies. It uses a flyback converter topology and provides constant-voltage control. The device includes an internal high-voltage power MOSFET and integrated control functions, helping reduce circuit complexity in compatible designs.

This component is intended for use by electronics manufacturers, repair technicians, maintenance professionals, and electronic component suppliers. Before selecting it as a replacement, users should verify the original component number, package, pin configuration, and circuit requirements.

Key Features and Benefits

Integrated Switching Design

The LNK626PG combines switching and control functions within one IC. This integration can help simplify the overall design of a compatible power supply and reduce the need for separate control circuitry.

Constant-Voltage Control

The device is designed to support constant-voltage power conversion. Proper circuit design and component selection are essential to achieve the required output regulation and performance.

Built-In Protection Functions

The IC includes protection features such as over-temperature response and protection against output short-circuit and control-loop fault conditions. These functions are designed to support safer, more reliable operation when the device is used within its specified operating limits.

Power Supply Design Flexibility

Its flyback topology makes the device suitable for certain low-power AC-DC converter designs. The final power capability depends on the input range, transformer and other external components, thermal conditions, and whether the power supply is open-frame or enclosed.

Compact Component Format

The LNK626PG is available in a through-hole PDIP-8C package format. This can be useful for compatible printed circuit board layouts and service or repair work where the original design uses the same package.

Replacement and Compatibility Guidance

When choosing an LNK626PG IC, confirm that the marking on the original component matches the required model. Check the package style, pin arrangement, circuit topology, and manufacturer documentation. A component with a similar appearance or a related part number is not necessarily a suitable substitute.

Power supply circuits can contain hazardous voltages even after being disconnected from the mains. Installation and testing should be carried out by a suitably qualified person using appropriate electrical safety procedures. Do not handle or replace the IC while the equipment is connected to a power source.

Superway recommends verifying compatibility before purchase to help reduce incorrect orders and unnecessary repair delays. If the original part number is unclear, consult the equipment service documentation or a qualified electronics technician.

Wholesale Price

Wholesale pricing may depend on order quantity, stock availability, component condition, and supplier terms. For bulk requirements, confirm the available quantity and final price before placing an order. Any price or availability shown on the product page should be checked at the time of purchase.

Superway provides this product listing to help buyers identify the LNK626PG IC by its model number and intended component type. Please verify the product description and ordering details before completing your purchase.

Why Choose the LNK626PG IC?

Selecting the correct power supply IC can help make repair and maintenance work more straightforward. The LNK626PG integrates switching and control functions in a single component and is designed for compatible constant-voltage AC-DC converter applications. Its protection features and established product family make it a relevant option when the original circuit specifically calls for this model.

For replacement work, matching the original part number is more important than choosing a component based only on appearance. Confirm the required model and specifications before installation.

Superway aims to provide clear product identification so buyers can find electronic components according to their model number and application. Review the product details, verify compatibility, and seek technical assistance when the circuit requirements are uncertain.

Important: Product performance depends on correct circuit design, installation, and operating conditions. Confirm authenticity, package markings, and the manufacturer’s datasheet before use.
