TEA1623P/N1,112

Overview

The TEA1623P/N1,112 is an offline flyback converter IC from NXP's STARplug series. It operates within a switching frequency range of 10kHz to 200kHz and supports a supply voltage (Vcc/Vdd) of 7.5V to 40V. The device features an internal switch with a breakdown voltage of 650V and a startup voltage of 9.5V. It utilizes pulse width modulation control with a maximum duty cycle of 75%. Packaged in an 8-DIP (0.300") through-hole format, it includes fault protection mechanisms such as current limiting, over-temperature, and short-circuit protection. The component is rated for operation between -20°C and 85°C.

• Integrated high-voltage power switch with 650V breakdown capability
• Frequency-controlled flyback topology with adjustable switching range
• Comprehensive fault protection including over-temperature and short-circuit safeguards

Applications

• Offline AC-DC power supplies
• Flyback converter designs
• General-purpose switched mode power supplies

Procurement Notes

Verify the specific suffix N1,112 against official NXP documentation to confirm package and environmental compliance details. Note that this product status is listed as discontinued or obsolete; ensure availability through authorized channels or consider valid replacement options if long-term supply is required. Cross-reference the manufacturer part number with distributor codes to avoid ordering errors.

Selection Notes

Select this component for applications requiring a simple, integrated flyback solution with moderate power levels. The fixed 8-DIP package suits prototyping and low-volume production where surface-mount space is not critical. Ensure the input voltage range aligns with the 7.5V to 40V Vcc specification and that the thermal environment stays within the -20°C to 85°C operating limit.

Part Context

This part belongs to the TEA162x family of STARplug controllers, designed for cost-effective AC-DC conversion. It shares architectural similarities with other members like the TEA1622P but may differ in specific electrical parameters or packaging variants. The family targets general consumer and industrial offline power applications requiring reliable performance with minimal external components.
