SLVSBV3B April 2013 – November 2016 TPS56528
PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | EN | I | Enable input control. EN is active high and must be pulled up to enable the device. |
2 | VFB | I | Converter feedback input. Connect to output voltage with feedback resistor divider. |
3 | VREG5 | O | 5.5-V power supply output. A capacitor (0.47 µF typical) must be connected to GND. VREG5 is not active when EN is low. |
4 | PG | O | Open-drain power good output. |
5 | GND | — | Ground pin. Power ground return for switching circuit. Connect sensitive SS and VFB returns to GND at a single point. |
6 | SW | O | Switch node connection between high-side NFET and low-side NFET. |
7 | VBST | O | Supply input for the high-side FET gate drive circuit. Connect 0.1-µF capacitor between VBST and SW pins. An internal diode is connected between VREG5 and VBST. |
8 | VIN | I | Input voltage supply pin. |
— | PowerPAD | — | Thermal pad of the package. This pad must be soldered to achieve appropriate dissipation and must be connected to GND. |
