LM2576HVSX-ADJ 描述
(2) Operating method The LD shall change its forward voltage requirement and optical output power according to temperature change. Also, the LD will require more operation current to maintain same output power as it degrades. In order to maintain output power, use of APC (Automatic Power Control) is recommended, which use monitor feedback to adjust the operation current. Confirm that electrical spike current generated by switching on and off does not exceed the maximum operating current level specified herein above as absolute max rating. Also, employ appropriate countermeasures to reduce chattering and/or overshooting in the Circuit.
LM2576HVSX-ADJ 特点
Sync detect C Output to signal when the link is active or inactive. The link is considered to be active when DE is actively switching. The LM2576HVSX-ADJ/201A monitors the state DE to determine link activity. SCDT can be tied externally to PDO to power down the output drivers when the link is inactive.
LM2576HVSX-ADJ 应用
The CD54/74FCT245 is a noninverting, three-state, bidirec- tional transceiver/buffer intended for two-way transmission fromA bus to B bus or B bus to A bus. The logic level present on the Direction Input (DIR) determines the data direc- tion. When the Output Enable input is HIGH, the outputs are in the high impedance state.
