PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NUMBER | ||
EN | 1 | I | Enable. Pull High to enable converter. |
SDA | 2 | I/O | Data I/O terminal. |
SCL | 3 | I/O | Clock I/O terminal. |
A1, A0 | 4,5 | I | Chip address. |
VIN | 6 | I | Supply Input for 5.5V linear regulator. |
PVIN | 7,8 | I | Power inputs and connects to high side MOSFET drains. |
PGND | 9,10 | I/O | Ground returns for low-side MOSFETs. Input of current comparator. |
SW | 11,12,13 | I/O | Switch node connections for both the high-side NFETs and low-side NFETs. Input of current comparator. |
VBST | 14 | I | Supply input for high-side NFET gate drive circuit. Connect 0.1µF ceramic capacitor between VBST and SW terminals. An internal diode is connected between VREG5 and VBST. |
PGOOD | 15 | O | Open drain power good output. Low means the output voltage of the corresponding output is out of regulation. |
VREG5 | 16 | O | Output of 5.5V linear regulator. Bypass to GND with a high-quality ceramic capacitor of at least 2.0µF ceramic capacitor. Do not connect any other circuitry to the terminal. VREG5 is active when EN is H-level. |
GND | 17 | I/O | Signal GND. Connect sensitive SS and VFB returns to GND at a single point. |
SS | 18 | O | Soft-Start Programming terminal. Connect Capacitor from SS terminal to GND to program Soft-Start time. |
VOUT | 19 | I | Connection to output voltage |
VFB | 20 | I | D-CAP2 feedback input. Connect to output voltage with resistor divider. |
Exposed Thermal Pad | Back side | I/O | Thermal pad of the package. Must be soldered to achieve appropriate dissipation. Must be connected to GND. |
