文档介绍：NXP 公司的 TEA1836XT 是高性能低成本 DCM 反激转换器控制器, 所有功率水平都提供高效率和很低的功耗, 输出功率高达 75W, 主要用在笔记本适配器, 打印机,TV 和计算机监视器. 本文介绍了 TEA1836X T 通用特性, 绿色特性和保护特性, 应用框图, 典型应用电路, 以及采用 TEA1836XT + TEA1792T 的 65 W 笔记本适配器 TEA1836DB1094 输入和输出指标, 电路图, 材料清单,PCB 布局图和变压器数据图. The TEA1836XT isa high-featured low-cost DCM flyback converter controller. It provides a high efficiency at all power levels and very low no-load power consumption at nominal output voltage using burst mode mode is enhanced to minimize the risk of audible noise. The TEA1836XT is intended for power supplies up to 75 W that require extended high peak power capabilities in order to supply high power without requiring a applications are notebook adapters, printers, TVs puter monitors. The TEA1836XT isa controller IC for low-cost Switched Mode Power Supplies (SMPS) intended for flyback topologies. The built-in green functions provide high efficiency at all power levels. At high power levels the flyback operates in QR mode. When lowering the power levels, the controller switches to DCM or Frequency Reduction (FR) mode. The peak current is reduced to 25 % of the maximum peak current. At low power levels, when the flyback switching frequency reaches 25 kHz, the flyback converter switches to burst mode. To ensure high efficiency at low power and excellent no-load power performance, a burst mode has been integrated that reduces
