1 General description

The TEA18363T is a controller IC for low-cost switched-mode power supplies (SMPS). It

is intended for flyback topologies. The built-in green functions provide high efficiency at

all power levels.

At high power levels, the flyback operates in quasi-resonant (QR) mode. At lower power

levels, the controller switches to frequency reduction (FR) or discontinuous conduction

mode (DCM) and limits the peak current to approximately 25 of the maximum peak

current. Valley switching is used in all operating modes.

At low power levels, when the flyback switching frequency drops below 25 kHz, the

flyback converter switches to burst mode. A special burst mode has been integrated

which reduces the optocurrent to a minimum level, ensuring high efficiency at low power

and excellent no-load power performance. As the switching frequency in this mode has a

minimum value of 25 kHz while the burst frequency is below 800 Hz, the frequencies are

outside the audible range. During the non-switching phase of the burst mode, the internal

IC supply current is minimized for further efficiency optimization.

The TEA18363T includes an accurate overpower protection (OPP). The OPP enables

the controller to operate in overpower situations for a limited time. If the output is shorted,

the system switches to low-power mode where the output power is limited to a lower

level.

The TEA18363T is manufactured in a high-voltage silicon-on-insulator (SOI) process.

The SOI process combines the advantages of a low-voltage process (accuracy, highspeed

protection, functions, and control), while maintaining the high-voltage capabilities

(high-voltage start-up, low standby power, and an integrated X-capacitor discharge

function).

The TEA18363T enables low-cost, highly efficient, and reliable supplies for power

requirements up to 75 W to be designed with a minimum number of external

components.

All values mentioned in this data sheet are typical values, unless otherwise specified.
