Description

I’m not sure which exact TEA1833LTS/1H variant you have, but here’s a concise intro:
- TEA1833LTS/1H is an offline switch‑mode controller in the TEA family used in small AC–DC power supplies and LED drivers.
- It typically provides primary‑side regulation, current‑mode control, and protection features (UVLO, OVP, OTP, OCP).
- Some variants include an integrated high‑voltage MOSFET; others require an external FET.
- The LTS/1H suffix denotes a specific package/lead‑free/industrial variant.
Common applications: compact adapters, set‑top/AV power supplies, LED backlight drivers.
For exact details (pinout, supply and FET ratings, protection thresholds), consult the official datasheet for your exact part variant. If you can share the manufacturer or a link, I can pull in precise specs.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SO-8/D8 footprint).
- Function: Off-line switch-mode power-supply controller with an integrated high-voltage transistor, used for flyback converters. Provides PWM/current-mode regulation and protection (UVLO, OVP, current limit) for universal-input SMPS.

Manufacturer

Manufacturer: NXP Semiconductors.
What kind of company: NXP is a Dutch multinational semiconductor company that designs and manufactures integrated circuits and electronic components, focusing on automotive, secure connectivity, industrial, and IoT applications.

Application

TEA1833LTS/1H is an offline switch‑mode power‑supply controller (flyback topology). Typical applications include:
- LED lighting drivers (constant current)
- AC/DC adapters and mobile device chargers
- Power supplies for TVs/monitors and set‑top boxes
- Small industrial/power supplies and general consumer electronics
Designed for low‑ to medium‑power offline SMPS.
