Description (Refer to Figure 1)
This is the emitter of the internal switch. The saturation voltage V sat of this output switch is typically 1.0 V. It should be
kept in mind that the PCB area connected to this pin should be kept to a minimum in order to minimize coupling to
sensitive circuitry.
This pin is the positive input supply for the LM2595 step ? down switching regulator. In order to minimize voltage transi-
ents and to supply the switching currents needed by the regulator, a suitable input bypass capacitor must be present
(C in in Figure 1).
Circuit ground pin. See the information about the printed circuit board layout.
This pin is the direct input of the error amplifier and the resistor network R2, R1 is connected externally to allow pro-
gramming of the output voltage.
It allows the switching regulator circuit to be shut down using logic level signals, thus dropping the total input supply
current to approximately 50 m A. The threshold voltage is typically 1.6 V. Applying a voltage above this value (up to
+V in ) shuts the regulator off. If the voltage applied to this pin is lower than 1.6 V or if this pin is left open, the regulator
will be in the “on” condition.
