Features & Applications

The TEA1723DT/N1,118 is a low cost switched mode power supply (SMPS)controller IC for low power applications (up to 11 W), operates directly from the rectified universal mains input.

It includes a high voltage power switch (700 V) and optimized for a flyback converter topologies to provide high-efficiency over the entire load range with ultra-low power consumption in the no-load condition.

Features:

Low power SMPS controller with integrated power switch
700 V high voltage power switch
Primary sensing for control the output voltage without optocoupler and secondary feedback circuitry
Minimizes audible noise in all operation modes
Jitter function for reduced EMI
Enables no-load power consumption < 35 mW
Very low supply current in no-load condition with energy saver mode
Incorporates a high voltage start-up circuit with zero current consumption undernormal switching operation
Available in halogen-free and Restriction of Hazardous Substances (RoHS) SO7 package
OverVoltage Protection (OVP) on Feedback control (FB) pin with auto-restart
UnderVoltage LockOut (UVLO) protection on IC supply pin
OverTemperature Protection (OTP)
Soft-start by reduced peak current for zero and low output voltage
Demagnetization protection for guaranteed discontinuous conduction mode operation
Open and short-circuit protection of the Feedback control (FB) pin
Short-circuit protection of the charger output

Applications:

Battery chargers for cellular phones
Standby supply for TV and desktop PC
Power supply for white goods applications
