TEA1623PH/N1,112

Overview

The TEA1623PH/N1,112 is an offline flyback converter IC from the STARplug series by NXP USA Inc. It operates within a switching frequency range of 10kHz to 200kHz and features a maximum duty cycle of 75%. The device supports a supply voltage (Vcc/Vdd) between 7.5V and 40V, with a startup voltage of 9.5V. It includes an internal switch rated for 650V breakdown voltage. Packaged in an 8-DIP format, it provides isolation and incorporates fault protection mechanisms including current limiting, over-temperature, and short-circuit safeguards.

Feature Summary

• Integrated high-voltage startup source simplifies design by eliminating external bias components
• Built-in protections ensure reliability against over-current, thermal overload, and output short circuits
• Frequency control capability allows operation across a wide switching range to optimize efficiency

Applications

• Offline AC/DC power supplies using flyback topology
• Consumer electronics requiring isolated power conversion
• General-purpose switched mode power supply designs

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm package integrity and pin alignment upon receipt. Check RoHS compliance documentation as required by regional regulations. Ensure storage conditions meet moisture sensitivity level specifications to prevent damage before soldering.

Selection Notes

Select this component for applications requiring a simple, cost-effective flyback solution with integrated high-voltage startup. Consider the 8-DIP package for through-hole mounting requirements. Evaluate the 650V switch rating against peak voltage stresses in the specific transformer design. Verify that the operating temperature range meets environmental constraints.

Part Context

The TEA1623P belongs to NXP's STARplug family of single-stage PFC controllers combined with flyback regulation. This series targets low-to-medium power applications where simplicity and component count reduction are critical. The TEA1623 variant specifically offers flyback control without the integrated PFC stage found in other family members, providing flexibility for standard isolated converter topologies.
