Overview
TEA1733AT GreenChip SMPS control IC Rev.
3 — 24 May 2013 Product data sheet 1.
General description The TEA1733AT is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies.
It operates in fixed frequency mode.
Frequency jitter has been implemented to reduce ElectroMagnetic Interference (EMI).
Slope compensation is integrated for Continuous Conduction Mode (CCM) operation.
The TEA1733AT IC includes OverPower Protection (OPP).
This enables the controller to operate under overpower situations for a limited amount of time.
Two pins, VINSENSE and PROTECT, are reserved for protection purposes.
Input UnderVoltage Protection (UVP) and OverVoltage Protection (OVP), output 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 and the switching frequency is reduced to limit switching losses.
The combination of fixed fre...
