3 / 21 page L5973AD Pin settings 3/21 1 Pin settings 1.1 Pin connection Figure 1. Pin connection (top view) 1.2 Pin description OUT SYNC INH COMP 1 3 2 4 VCC VREF GND FB 8 7 6 5 D98IN955 Table 1. Pin description N° Type Description 1 OUT Regulator output. 2 SYNC Master/Slave Synchronization. When it is open, a signal synchronous with the turn-off of the internal power is present at the pin. When connected to an external signal at a frequency higher than the internal one, then the device is synchronized by the external signal. Connecting together the SYNC pin of two devices, the one with the higher frequency works as master and the other one, works as slave. 3INH A logical signal (active high) disables the device. With IHN higher than 2.2V the device is OFF and with INH lower than 0.8V, the device is ON. If INH is not used the pin must be grounded. When it is open, an internal pull- up disables the device. 4 COMP E/A output to be used for frequency compensation. 5FB Stepdown feedback input. Connecting the output voltage directly to this pin results in an output voltage of 1.235V. An external resistor divider is required for higher output voltages (the typical value for the resistor connected between this pin and ground is 4.7K). 6 VREF Reference voltage of 3.3V. No filter capacitor is needed to stability. 7 GND Ground. 8 VCC Unregulated DC input voltage. |
