TEA1732LTS: GreenChip SMPS control IC
The TEA1732LTS is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. The TEA1732LTS 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 (CCM) operation.
The TEA1732LTS IC features OverPower Protection (OPP). The controller accepts an overpower situation for a limited amount of time.
Mains undervoltage protection (brownout), output OverVoltage Protection (OVP), and OverTemperature Protection (OTP) can be implemented using a minimal number of external components.
At low-power levels, the primary peak current is set to 25 % 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 TEA1732LTS makes the design of low-cost, highly efficient and reliable supplies for power requirements up to 75 W easier by requiring a minimum number of external components.
