TEA1993TS/1

TEA1993TS/1 is a Philips/NXP TEA199x family offline switch‑mode power‑supply controller. It targets low‑to‑medium power flyback converters (adapters, power supplies, LED drivers) and integrates high‑voltage startup, current sensing, control logic, and protection features (overcurrent/short‑circuit, overvoltage, thermal). The device drives an external power MOSFET (or, in some variants, includes one) to switch the primary of a transformer and regulate the output via PWM. Typical options include fixed switching frequency and protection latch behavior, suitable for compact, safe SMPS designs.
Key points:
- Primary‑side controller for flyback topologies
- High‑voltage startup and current‑sense
- Protections: OVP, current limit, thermal shutdown
- External MOSFET driver (in many configurations)
- Usually implemented in an 8‑pin package
Use when designing offline power supplies or LED drivers that require integrated control with robust protection. For exact pinout, electrical specs, and application circuits, refer to the TEA1993TS/1 datasheet and evaluation boards. If you share a link or the datasheet, I can summarize the specifics.

Manufacturer: NXP Semiconductors (originally Philips Semiconductors).
What kind of company: NXP is a Dutch multinational semiconductor company that designs and manufactures integrated circuits and system-level solutions (analog, mixed-signal, MCU, RF, power management, connectivity) for automotive, industrial, mobile, and consumer electronics markets.

TEA1993TS/1 is a high‑voltage triac/thyristor gate‑driver. Applications include AC mains control: light dimmers, motor and appliance control, heater regulation, and line‑side switching in SMPS/off‑line power supplies.

I don’t have a verified direct equivalent for TEA1993TS/1 without the manufacturer or datasheet. Please provide the maker, full datasheet or a photo of the marking. Alternatively, check NXP/Philips TEA1993 family listings, distributor cross‑reference tools (Mouser/Octopart/DatasheetArchive) or share the IC’s function and pinout and I’ll find compatible substitutes.
