Function Description
Switch terminal for DC/DC converter. Nch MOSFET built-In.
Over voltage protection terminal. IC switching operation is disabled when OVP terminal voltage is over
32.5 V (TYP.).
If the voltage returns to 31.5V (TYP) or less, operation is enabled again.
LED IF setting resistor connecting terminal.
This is a terminal to connect capacitance for soft-start function.
If capacitance is no connecting in this terminal, IC operates without soft-start function.
Voltage-input terminal for IC-enable.
High: Operation mode
Low: Shutdown mode
If EN input is open, IC operation becomes unsettled. EN input must be fixed to High or Low.
Supply voltage input terminal. (2.8 V to 5.5 V)
Connect to resistance for internal frequency setup. (0.2 to 2MHz)
Ground terminal.
