Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | The drain of the internal 5A, 24V power MOSFET switch connected to the boost or SEPIC inductor or flyback transformer. |
| 2 | VIN | power_in | Input supply pin; connect to supply voltage between 2.9 V and 16 V. |
| 3 | EN | input | Enable pin; when voltage falls below enable threshold approximately 0.92 V for more than 1 ms, the IC turns off. |
| 4 | SS | input | Soft-start programming pin; connect capacitor between SS and AGND to program soft-start timing with internal 6 µA charging current. |
| 5 | SYNC | input | Switching frequency synchronization pin accepting external clock signal from 0 V to 5 V with logic levels (high ≥1.2 V, low ≤0.4 V) to set frequency between 200 kHz and 1 MHz; tie to AGND if not used. |
| 6 | AGND | power_in | Signal ground of the IC providing reference for control circuits. |
| 7 | COMP | output | Output of the transconductance error amplifier with clamp voltage ranging from 0.75 V to 3.1 V; connect external RC compensation network to this pin. |
| 8 | FB | input | Voltage feedback input to error amplifier regulated to 1.229 V reference; connect to center tap of resistor divider to program output voltage. |
| 9 | FREQ | input | Switching frequency programming pin; connect external resistor to AGND to set switching frequency from 100 kHz to 1.2 MHz with internal 1.25 V reference voltage. |
| 10 | NC | unconnected | Reserved pin; must be connected to AGND. |
| 11 | PGND | power_in | Power ground connected to source of internal power MOSFET switch; high current return path for power stage. |
| 12 | PGND | power_in | Power ground connected to source of internal power MOSFET switch; high current return path for power stage. |
| 13 | PGND | power_in | Power ground connected to source of internal power MOSFET switch; high current return path for power stage. |
| 14 | NC | unconnected | Reserved pin; must be connected to AGND. |
| 15 | SW | output | The drain of the internal 5A, 24V power MOSFET switch connected to the boost or SEPIC inductor or flyback transformer. |
| 16 | SW | output | The drain of the internal 5A, 24V power MOSFET switch connected to the boost or SEPIC inductor or flyback transformer. |
| 17 | PowerPAD | power_in | Thermal pad; solder to AGND for enhanced power dissipation using thermal vias to internal ground plane. |
