TEA1571T - Brand New NXP Semiconductors IC Chips
-
Description
The TEA1571T is a low power member of the GreenChip family and is specially designed for standby Switched Mode Power Supply (SMPS) applications. It incorporates all the necessary functions for an efficient and low-cost power supply for a universal input range of 90 V to 276 V AC. The TEA1571T is a monolithic integrated circuit available in a SO8 package. With only seven functional pins, it provides extensive control functions to form a flexible and reliable power supply with minimal external components. The TEA1571T operates in a flyback topology with a fixed switching frequency, constant primary peak current control, and regulates the output voltage in Burst mode.
Specifications and features
