Abstract
TheTEA1836XT is a high-featured low-cost DCM/QR flyback converter
controller. It provides high efficiency at all power levels including very low
no-load power consumption at nominal output voltage in burst mode
operation.
To minimize the risk of audible noise, burst mode operation is included for
the low load range. Switching in the audible frequency range is limited and
peak currents are low.
The TEA1836XT is intended for power supplies up to 75 W with extra high
peak power capabilities to enable supplying high peak power equipment
without requiring a PFC.
This document describes the 65 W notebook adapter demo board with the
TEA1836XT and TEA1792TS. The demo board provides an output of
19.5 V/3.34 A.
The average efficiency is above 91 % and the no-load power consumption
is below 30 mW.

5.12 Overvolt age protection
Applying a short circuit across the opto-LED of the optocoupler (U1B; see Figure 20)
creates an output overvoltage condition. The overvoltage protection is triggered when the
AUX pin voltage increases to 3 V during the OVP detection interval. The output voltage
was measured directly at the output connector for both a nominal load (3.34 A) and a
no-load condition.

This is the time between the mains voltage switching on and the nominal output power
available at the output.

The shape of the output voltage during start-up was measured for 90 V/60 Hz and
264 V/50 Hz directly at the output connector for a no-load and a nominal load (3.34 A)
condition.
