PRODUCTION DATA.
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | EN | I | Enable pin |
| 2 | PG | O | Power good output flag. Open drain output. Pull up to an external rail through a resistor. |
| 3 | VIN | P | Gate driver supply and power conversion voltage |
| 4 | VIN | P | Gate driver supply and power conversion voltage |
| 5 | VIN | P | Gate driver supply and power conversion voltage |
| 6 | VIN | P | Gate driver supply and power conversion voltage |
| 7 | PGND | P | Device power ground terminal |
| 8 | PGND | P | Device power ground terminal |
| 9 | PGND | P | Device power ground terminal |
| 10 | PGND | P | Device power ground terminal |
| 11 | PGND | P | Device power ground terminal |
| 12 | PGND | P | Device power ground terminal |
| 13 | SW | O | Output inductor connection to integrated power devices |
| 14 | SW | O | Output inductor connection to integrated power devices |
| 15 | SW | O | Output inductor connection to integrated power devices |
| 16 | SW | O | Output inductor connection to integrated power devices |
| 17 | VBST | P | Supply input for high-side MOSFET (bootstrap terminal). Connect capacitor from this pin to SW terminal. |
| 18 | BP7 | P | Bias for internal circuitry and driver |
| 19 | BP3 | P | Input bias supply for analog functions |
| 20 | AGND | G | Device analog ground terminal |
| 21 | RT/SYNC | I/O | Synchronized to external clock. Program the switching frequency by connecting with a resistor to GND. |
| 22 | MODE/SS | I | Mode configuration pin. Connect with a resistor to GND sets different modes and soft-start time, parallel a capacitor (or no capacitor) with the resistor changes the current limit threshold. Shorting MODE/SS pin to supply inhibits the device; shorting MODE/SS pin to AGND is equivalent to 10-kΩ resistor setting is not recommended (see Table 1 and Table 2 for resistor and capacitor settings). |
| 23 | COMP | O | Error amplifier compensation terminal. Type III compensation method is generally recommended for stability. |
| 24 | FB | I | Voltage feedback pin. Use for OVP, UVP, and power good determination |
