TEA1836DB1094 TEA1836XT + TEA1792T 65 W notebook adapter Rev. 1 - 4 December 2013 User manual Document information Info Keywords Content TEA1836DB1094, TEA1836XT, very low standby power consumption, high peak power, active X-cap discharge, burst mode operation, flyback converter, 65 W, notebook adapter, controller, converter, power supply, demo board The TEA1836XT 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 m W. Abstract http://..
