LLP8 Package NS Package Number SDA08A
Description
Power Ground Pin.
Switching node connection to the internal PFET switch and NFET synchronous rectifier.
Mode Control Pin: > 1.0V selects continous PWM mode ; <0.4V selects Auto (PFM-PWM)
mode. Do not leave this pin floating.
Feedback analog input. Connect directly to the output filter capacitor for fixed voltage
versions. For adjustable version external resistor dividers are required (Figure 2). The
internal resistor dividers are disabled for the adjustable version.
Enable pin. The device is in shutdown mode when voltage to this pin is <0.4V and enabled
when >1.0V. Do not leave this pin floating.
Not Connected. Leave Pin Floating. Do Not Connect to other pins
Signal Ground Pin.
Power Supply input. Connect to the input filter capacitor (Figure 1).
