Notes:

a. Limits are guaranteed by testing.

b. Typical values are derived from the mean value of a large quantity of samples tested during characterization and represent the most likely

expected value of the parameter at room temperature.

PIN CONFIGURATION

DETAILED PIN DESCRIPTION

LX: Drain of the Internal 26 V NMOS. Connect inductor/

diode to LX. Minimize trace area at this pin to keep electro-

magnetic interference down to a minimum.

capacitor is required on this pin.

SHD: the SHD pin provides shutdown control. To allow for

to disable the device.

FB: The inverting input of the voltage error amplifier. This is

internally compared against a voltage of 0.208 V appearing

on the voltage error amplifier's non-inverting input. External

resistors are connected to this pin to set the regulated output

voltage.

slop compensation.

GND: This pin acts as both the analog ground and the power

ground for this part.
