2 / 16 page ![]() High Efficiency 1.5MHz, Step up Regulator EC9210 E-CMOS Corp. (www.ecmos.com.tw) Page 2 of 16 5E29N-Rev.F002 Pin Configurations Figure 2 Pin Configuration of EC9210(Top View) Pin Description Pin Number Pin Name Description 1 LX Switch pin. Connect this pin to inductor/diode here. 2 GDN GND 3 FB Feedback Input. The device senses feedback voltage via FB and regulate the voltage at 1.23V. Connecting FB wi th a resistor‐divider from the output that sets the output voltage. 4 EN Enable Control Input. Forcing this pin above 1.0V enables the device. Forcing this pin below 0.4V to shut it down. In shutdown, all functions are disabled to decrease the supply current below 1μA. Do not left this pin floating. 5 IN Main Supply Pin. Must be closely decoupled to GND with a 2.2μF or greater ceramic capacitor. |
