TEA152X and TEA162X are integrated circuits produced by Philips Corporation for switch-mode power supply design. They feature low cost, low power consumption, high efficiency, light load to empty load automatic frequency reduction, direct high voltage start-up, flexible application design, and additional protection functions.
The TEA152X and TEA162X are low‑cost, low‑power SMPS controller ICs designed for standby and charger applications. They include built‑in protection functions such as OVP, OCP, OTP and thermal shutdown, and operate with a wide input voltage range.
Typical uses include mobile phone chargers, DVD/Set‑Top‑Box adapters, LCD‑TV and projector standby supplies. The devices provide low standby power (< 100 mW) and feature auto‑restart and UVLO functions for reliable operation.
| Typical charge current (TEA152X) | 4 mA |
|---|---|
| Typical charge current (TEA162X) | 500 µA |
| No‑load power consumption | < 100 mW |
| Input voltage range | 10 kΩ ~ 200 kΩ (ESA) |
The TEA152X typically charges at 4 mA.
The TEA162X typically charges at 500 µA.
The no‑load power consumption is less than 100 mW.
The ICs provide over‑voltage (OVP), over‑current (OCP), over‑temperature (OTP) and standby (SWP) protection.
