The TEA1832LTS is a low-cost Switched Mode Power Supply (SMPS) controller IC
intended for flyback topologies. The TEA1832LTS operates in peak current and frequency
control mode. Frequency jitter has been implemented to reduce ElectroMagnetic
Interference (EMI). Slope compensation is integrated for Continuous Conduction Mode
The TEA1832LTS IC features OverPower Protection (OPP). The controller accepts an
overpower situation up to 200 % for a limited amount of time.
Mains undervoltage protection (brownin/brownout), output OverVoltage Protection (OVP),
and OverTemperature Protection (OTP) can be implemented using a minimal number of
At low-power levels, the primary peak current is set to 22 % of the maximum peak current.
The switching frequency is reduced to limit the switching losses. The combination of fixed
frequency operation at high output power and frequency reduction at low output power
provides high efficiency over the total load range.
The TEA1832LTS makes the design of low-cost, highly efficient and reliable supplies
easier by requiring a minimum number of external components. The device is especially
suited for medium power applications.
