SLVS751E November 2007 – January 2024 TPS5430-Q1
PRODUCTION DATA
PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | BOOT | O | Boost capacitor for the high-side FET gate driver. Connect 0.01-μF low ESR capacitor from BOOT pin to PH pin. |
2, 3 | NC | — | No connect, not IO |
4 | VSENSE | I | Feedback voltage for the regulator. Connect to output voltage divider. |
5 | ENA | I | On and off control. Below 0.5 V, the device stops switching. Float the pin to enable. |
6 | GND | — | Ground. Connect to DAP. |
7 | VIN | I | Input supply voltage. Bypass VIN pin to GND pin close to device package with a high-quality low-ESR ceramic capacitor. |
8 | PH | O | Source of the high side power MOSFET. Connected to external inductor and diode. |
— | DAP | — | GND pin must be connected to the exposed pad for proper operation. |
