Introduction

AI Translation

TEA1832LTS is a low-cost SMPS controller IC designed for flyback topology. It operates in peak current and frequency control mode, employs frequency jitter to reduce EMI, and integrates slope compensation for CCM operation. The IC features over-power protection (OPP), allowing the controller to withstand up to 200% over-power conditions for a limited duration. Mains brownin/brownout protection, output OVP, and OTP can be implemented with a minimum number of external components. At low power levels, the primary peak current is set to 22% of the maximum peak current, and the switching frequency is reduced to limit switching losses. The combination of fixed-frequency operation at high output power and frequency reduction at low output power enables high efficiency across the entire load range. By using a minimum number of external components, the TEA1832LTS simplifies the design of low-cost, efficient, and reliable power supplies, making it particularly suitable for medium-power applications.
