PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
EN | 1 | I | Enable Input. Set this digital input higher than 1.2 V for normal operation. For shutdown, set low. Pin is internally pulled up to VIN and can be left floating for always-on operation. |
VCON | 2 | I | Output voltage control pin. Connect to analog voltage from resisitve divider or DAC/controller to set the VOUT voltage. VOUT = 2.5 x VCON. Connect a small (470pF) capacitor from this pin to SGND to provide noise filtering. |
FB | 3 | I | Feedback of the error amplifier. Connect directly to output capacitor to sense VOUT. |
SGND | 4 | I | Ground for analog and control circuitry. Connect to PGND at a single point. |
VOUT | 5 | O | Output Voltage. Connected to one terminal of the integrated inductor. Connect output filter capacitor between VOUT and PGND. |
PGND | 6 | I | Power ground for the power MOSFETs and gate-drive circuitry. |
VIN | 7 | I | Voltage supply input. Connect ceramic capacitor between VIN and PGND as close as possible to these two pins. Typical capacitor values are between 4.7 µF and 22 µF. |
VREF | 8 | O | 2.35-V voltage reference output. Typically connected to VCON pin through a resistive divider to set the output voltage. |
PAD | I | The center pad underneath the SIL0008A package is internally tied to SGND. Connect this pad to the ground plane for improved thermal performance. |
