ZHCSQS5F April 2006 – January 2024 TPS5420
PRODUCTION DATA
| TERMINAL | DESCRIPTION | |
|---|---|---|
| NAME | NO. | |
| BOOT | 1 | Boost capacitor for the high-side FET gate driver. Connect 0.01 μF low ESR capacitor from BOOT pin to PH pin. |
| NC | 2, 3 | Not connected internally. |
| VSENSE | 4 | Feedback voltage for the regulator. Connect to output voltage divider. |
| ENA | 5 | On/off control. Below 0.5 V, the device stops switching. Float the pin to enable. |
| GND | 6 | Ground. |
| VIN | 7 | Input supply voltage. Bypass VIN pin to GND pin close to device package with a high quality, low ESR ceramic capacitor. |
| PH | 8 | Source of the high side power MOSFET. Connected to external inductor and diode. |
