TOP271EG

The TOP271EG is a high-voltage gate driver optocoupler from Power Integrations. It is designed to provide isolated gate drive for power MOSFETs and IGBTs in a wide range of applications.

Description:

The TOP271EG is a high-voltage optocoupler that uses a GaAS infrared LED to transmit a signal from the input side to the output side, which is isolated from the input side by a high-voltage barrier. The output side features a high-voltage, open-collector output stage that can drive power MOSFETs and IGBTs with voltages up to 1200V.

Features:

• High-voltage isolation: The TOP271EG provides isolation of up to 5kV to ensure safe and reliable operation in high-voltage applications.
• High-voltage output: The output stage can drive power MOSFETs and IGBTs with voltages up to 1200V.
• Fast switching: The TOP271EG features fast switching times of 100ns, making it suitable for high-speed applications.
• Wide input voltage range: The input stage can operate from a wide range of input voltages, from 4.5V to 20V, making it suitable for a variety of power supply designs.
• Low input current: The input stage requires only 2mA of input current, reducing power consumption and improving efficiency.
• High output current: The output stage can sink up to 2A of current, making it suitable for driving large power MOSFETs and IGBTs.
