2) Input Voltage Range:4.2 to 18V
3) Feed Back Voltage:1.25±1.6%
4) Oscillating Frequency Variable:100 to 800kHz
5) Built-in Soft Start Function
6) Standby Current of 0 A (Typ.)
7) Built-in Master / Slave Function
8) Protection Circuit : Under Voltage Lockout Protection Circuit
Thermal Shutdown Circuit
Short Protection Circuit of Timer Latch type
9) MSOP8 Package
