TPS92410参考设计应用电路：

图1TPS92410内部结构图

TheTPS92410 is an advanced linear driver with high voltage start-up intended for use in low power, offline LED lighting applications. It can be used to regulate the average LED current through LEDs in conjunction with the TPS92411 direct drive switch.

TheTPS92410 device is a high-voltage linear regulator driver that can be used for offline LED drivers. It includes a feature that forces the regulator current to follow the rectified AC voltage to achieve high power-factor and low total harmonic distortion (THD). When the device detects multiple forward phase dimmer edges, the regulator current changes to a DC level to maintain a DC current draw to provide for a triac dimmer"s hold current requirements.
