LYT4214L

LYT4214L - LYTSwitch-4 Series AC-DC Offline Switching IC

The LYT4214L from Power Integrations is a high-performance AC-DC offline switching IC from the LYTSwitch-4 family, designed for isolated power supply applications up to 22W. Featuring an integrated 725V power MOSFET and advanced control circuitry, this IC enables compact, efficient flyback, buck, and boost converter designs with minimal external components.

Key Features & Benefits:

• Integrated 725V Power Switch - Reduces component count and board space
• 22W Output Power - Ideal for LED drivers, auxiliary supplies, and consumer electronics
• Multi-Topology Support - Flyback, step-down (buck), and step-up (boost) configurations
• 140kHz Switching Frequency - Enables use of smaller magnetics
• 99.9% Maximum Duty Cycle - Optimizes efficiency across load range
• Wide Operating Temperature - -40°C to 150°C (TJ) for industrial applications
• eSIP-7F Package - Through-hole mounting with exposed pad for thermal management

Typical Applications:

• LED lighting drivers and ballasts
• Auxiliary power supplies for appliances
• Standby and bias supplies
• Consumer electronics adapters
• Industrial control power modules
