Power Integrations AC/DC Converter 270 mA 50V 7-Pin SOIC LNK3205D-TL

Power Integrations LNK3205D-TL AC/DC Converter 270 mA 50V 7-Pin SOIC is a highly efficient power management IC designed for low component-count buck converters. It supports input voltages up to 265V AC and outputs a regulated 50V at up to 270 mA. The device operates at 66 kHz switching frequency with Flyback topology and a maximum duty cycle of 69%, providing excellent load and line regulation suitable for a wide range of industrial and commercial electronics.

The compact 7-pin SOIC package, measuring 4.9mm in length, 3.9mm in width, and 1.65mm in height, allows for space-saving PCB designs. Its operating temperature range from -40°C to 150°C ensures reliability under harsh environmental conditions.

The LNK3205D-TL features selectable device current limits that allow for the use of low-cost surface mount buck chokes, making it cost-effective without compromising performance. Frequency jittering significantly reduces EMI filter complexity, thereby improving electromagnetic compliance.

Protection features include auto-restart for short-circuit and open loop faults, and power delivery is limited to 3% of the maximum during fault conditions to protect the device and associated circuitry.

This AC/DC Converter supports buck, buck-boost, and flyback topologies with a low component count, making it ideal for industrial applications, power supplies, and consumer electronics.

Designers will benefit from the simplified pin-out that eases PCB heat sinking and reduced size and cost of magnetics and output capacitors. Supports maximum input voltage of 265V AC and minimum input voltage of 85V AC. Operates at 66 kHz frequency with accurate current limit for optimized power conversion.

Provides a stable maximum output current of 270 mA at 50V output voltage. Compact 7-pin SOIC package with dimensions ideal for surface mount applications. Wide operating temperature range from -40°C to 150°C ensures durability.

Auto-restart protection enhances device safety against faults. Low supply current of 141 μA to minimize power consumption. Frequency jittering reduces EMI filter complexity and cost. Compatible with buck, buck-boost, and flyback topologies for versatile use.
