TEA19363LT/1J

AC DC Converters, Offline Switchers Overview

The TEA19363LT/1J is a GreenChip family switched-mode power supply controller IC designed for flyback topologies. It features Quasi-Resonant (QR) and Discontinuous Conduction Mode (DCM) operation with active X-capacitor discharge. The device supports output voltages from 5 V to 20 V in Constant Voltage mode. Key electrical parameters include a startup voltage of 14.9 V, a Vcc/Vdd range of 0 V to 120 V, and a switching frequency range of 25.5 kHz to 128 kHz. It operates within a junction temperature range of -25°C to 125°C and includes protection against over-power, over-temperature, and over-voltage conditions.

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix /1J matches the required package and compliance specifications. Confirm that the active X-capacitor discharge feature aligns with safety standards for the target application. Ensure compatibility with secondary-side controllers if Constant Current regulation is required. Check for RoHS and REACH compliance documentation before finalizing procurement.

AC DC Converters, Offline Switchers Selection Notes

Select this component for flyback designs requiring QR/DCM operation and active discharge capabilities. Consider its compatibility with USB PD or smart charging controllers for enhanced functionality. Evaluate the 10-SO package constraints and thermal performance within the specified temperature range. Verify input voltage requirements against the 0 V to 120 V operating window.

AC DC Converters, Offline Switchers Part Context

The TEA19363LT/1J belongs to NXP's GreenChip family of SMPS controllers. It is engineered for high-efficiency flyback converters, often used in conjunction with secondary-side controllers like the TEA190x series. This integration supports advanced charging protocols and improves overall system performance in modern power adapters.

AC DC Converters, Offline Switchers Replacement Considerations

TEA19363T serves as a related variant without active X-capacitor discharge. TEA19362T offers fixed-frequency operation instead of QR/DCM. TEA19361T provides QR/DCM operation but lacks the active discharge feature. Verify functional differences before substitution.
