Product data sheet
1. General description
The TEA1733T 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 TEA1733T 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 TEA1733T 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.
2. Features and benefits
2.1 Features
SMPS controller IC enabling low-cost applications
Large input voltage range (12 V to 30 V)

A)
Low supply current during normal operation (typically 0.5 mA without load)
Overpower or high/low line compensation
Adjustable overpower time-out
Adjustable overpower restart timer
Fixed switching frequency with frequency jitter to reduce EMI
Frequency reduction with fixed minimum peak current to maintain high-efficiency at
low output power levels
Slope compensation for CCM operation
Low and adjustable OverCurrent Protection (OCP) trip level
