4 / 17 page Copyright © ANPEC Electronics Corp. Rev. A.3 - Jul., 2013 APL3546 www.anpec.com.tw 4 Pin Description FUNCTION NO. SOP-8 SOP-8P TDFN2x2-6 NAME 1 1 1 VIN Power Supply Input. Connect this pin to external DC supply. 2 2 2 SS Soft Start Control Pin. Connect a capacitor to GND to control the soft start rate. If the SS pin is left floating the soft start time is 2ms when VIN=12V. 3 3,9 3 GND GND 4 4 - NC No connection. 5 5 - NC No connection. 6 6 4 EN Enable Input. Pull this pin to high to enable the device and pull this pin to low to disable device. The EN pin cannot be left floating. 7 7 5 NC No connection. 8 8 6 VOUT Output Voltage Pin. The output voltage follows the input voltage. When EN is low the output voltage is discharged by an internal resistor. Electrical Characteristics(Cont.) Unless otherwise specified, these specifications apply over V IN=12V, VEN =5V. Typical values are at TA=25 oC. APL3546 Symbol Parameter Test Conditions Min. Typ. Max.
