TEA1833TS/1H Description

Short technical summary and product information.

The TEA1833TS/1H from NXP Semiconductors is a low-cost Switched Mode Power Supply (SMPS) controller IC specifically designed for flyback topologies. It operates in peak current and frequency control mode, incorporating frequency jitter to reduce ElectroMagnetic Interference (EMI) and integrated slope compensation for Continuous Conduction Mode (CCM) operation.

 

Key electrical features include a wide input voltage range of 10.5 V to 36 V and a maximum duty cycle of 90%. The device also includes integrated OverVoltage Protection (OVP) on the VCC pin and accurate OVP via the ISENSE pin. It supports OverPower Protection (OPP) up to 200% for a limited time, along with mains undervoltage protection, and OverTemperature Protection (OTP).

 

This SMPS controller IC is suited for medium power applications, enabling the design of cost-effective, highly efficient, and reliable power supplies with a minimal number of external components. It is available in a Surface Mount SC-74, SOT-457 package.
