FUNCTION
Shutdown Input. Drive SHDN low to force GATE and FLAG low and turn off the external n-channel
MOSFETs. Connect a 100k I resistor from SHDN to IN for normal operation.
Voltage-Divider Termination Output. TERM is internally connected to IN. TERM is high impedance when
SHDN is low, forcing the current to zero in the resistive-divider connected to TERM.
No Connection. Not internally connected.
Undervoltage Threshold Adjustment Input. Connect UVSET to the external resistive voltage-divider
network to adjust the desired input undervoltage threshold. Connect the resistive divider to TERM.
Overvoltage Threshold Adjustment Input. Connect OVSET to an external resistive voltage-divider
network to adjust the desired overvoltage disable or overvoltage limit threshold. Connect the
resistive divider to TERM for overvoltage switch-mode applications or to OUT for overvoltage limiting
applications.
Ground
Internally Connected. Connect to GND.
FLAG Output. During startup, FLAG is low as long as V OUT is lower than 90% of V IN and after that
it is high impedance. It asserts low during shutdown mode, an overvoltage, thermal shutdown, or
undervoltage fault or when V OUT falls below 90% of V IN .
Output Voltage-Sense Input. Connect OUT to the load with a 100 I series resistor. Bypass with a
minimum 10 F F capacitor to GND.
Source Input. Connect SRC to the common source connection of the external MOSFETs. When the
MOSFETs are turned off, this connection is clamped to GND. An external zener diode between SRC
and GATE protects the gates of the external MOSFETs.
Gate-Driver Output. Connect GATE to the gates of the external n-channel MOSFETs. GATE is the
charge-pump output during normal operation. GATE is quickly pulled low during a fault condition or
when SHDN is pulled low.
Positive Supply Input Voltage. Connect IN to the positive side of the input voltage. Bypass IN with a
0.1 F F ceramic capacitor to GND.
Exposed Pad. Can be connected to GND or left unconnected.
