TEA1733CP
GreenChip SMPS control IC
Rev. 2 — 15 July 2013
Product data sheet
1. General description
The TEA1733CP is a low cost Switched Mode Power Supply (SMPS) controller IC
intended for flyback topologies. It operates in fixed frequency mode. To reduce
ElectroMagnetic Interference (EMI), frequency jitter has been implemented. Slope
compensation is integrated for Continuous Conduction Mode (CCM) operation.
The TEA1733CP 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
frequency operation at high output power and frequency reduction at low output power
provides high-efficiency over the total load range.
The TEA1733CP enables low cost, highly efficient and reliable supplies for power
requirements up to 75 W to be designed easily and with a minimum number of external
components.
