Overview

The TEA1733CT 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 TEA1733CT 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 TEA1733CT 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.

Applications

All applications requiring efficient and cost-effective power supply solutions up to 75 W.

Key features

SMPS controller IC enabling low-cost applications
Large input voltage range (12 V to 30 V)
Very low supply current during start-up and restart (typically 10 μA)
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
Adjustable soft start operation
Two protection inputs (for example: for input UVP and OVP, OTP and output OVP)
IC overtemperature protection
