NAME | NO. | ||
EN/FLT | 1 | I/O |
Multi-functional enable input pin and output fault pin. Connect to microcontroller through an 18kΩ or greater pull-up resistor. Enable input pin: Forcing EN low disables the device. Pull high to enable normal device functionality. Fault output pin: This pin is pulled low for 200us to alert that power converter is shutdown due to a fault condition. |
VINP | 2 | P | Primary input supply voltage. Connect parallel 2.2nF 0402, and 10µF ceramic bypass capacitors close to VINP to GNDP pins. |
GNDP | 3, 4, 5, 6 | G | Power ground return connection for VINP. |
SEL | 7 | I | VCC selection pin. VCC setpoint is 5V when SEL is connected to VCC and 5.5V when SEL is shorted to GNDS. |
VCC | 8 | P | Isolated supply output voltage pin. Connect parallel 2.2nF 0402, and 22µF ceramic bypass capacitors close to VCC and GNDS pins. |
GNDS | 9, 10, 11, 12 | G | Power ground return connection for VCC. |
