PIN FUNCTION
Error amplifier output; place loop compensation components here
Bandgap reference bypass capacitor; typically 0.01μF to 0.047μF to SGND
Voltage feedback input; connected to external resistor divider between V OUT and SGND for adjustable
output; also used for speed-up capacitor connection
Output sense for fixed output; also used for speed-up capacitor connection
Junction temperature monitor output, connected to a 0.01μF - 0.047μF to SGND
Stress test enable; allows ±5% output movement; needs a pull-down resistor (1k - 100k); connect to
SGND if function is not used
Positive or negative voltage margining set pin; needs a pull-down resistor (1k - 100k); connect to SGND
if function is not used
Inductor drive pin; high current output whose average voltage equals the regulator output voltage
Not used
Ground return of the regulator; connected to the source of the low-side synchronous NMOS Power FET
Power supply input of the regulator; connected to the drain of the high-side PMOS Power FET
Control circuit positive supply; connected to V IN through an internal 20 Ω resistor
Power-good window comparator output; logic 1 when regulator output is within ±10% of target output
voltage
Chip enable, active high; a 2μA internal pull-up current enables the device if the pin is left open; a
capacitor can be added at this pin to delay the start of a converter
Auxilliary supply tracking positive input; tied to regulator output to synchronize start-up with a second
supply; leave open for standalone operation; 2μA internal pull-up current
Auxiliary supply tracking negative input; connect to output of a second supply to synchronize start-up;
leave open for standalone operation; 2μA internal pull-up current
Oscillator timing capacitor (see performance curves)
Control circuit negative supply or signal ground
