Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VREF | power_in | 2.0-V ±0.8% voltage reference output with 300-µA maximum current capability. |
| 2 | REFIN | input | Output voltage setting input; accepts 0.5-V to 2.0-V for programmable output voltage control. |
| 3 | GSNS | input | Ground sense input for differential feedback; short to GND if remote sensing not used. |
| 4 | VSNS | input | Voltage sense input for differential output voltage feedback at load point. |
| 5 | COMP | input | Compensation network connection for integrator feedback in control loop. |
| 6 | TRIP | input | Current sensing threshold configuration input with 10-µA source current and 4700-ppm/°C temperature coefficient. |
| 7 | GND | power_in | Analog ground reference; connect to quiet point on system ground plane. |
| 8 | PGND | power_in | Power ground return for low-side gate driver; connect as close as possible to device. |
| 9 | V5 | power_in | 5V power supply for internal circuits and gate drivers; operating range 4.5-V to 5.5-V. |
| 10 | DL | output | Low-side MOSFET gate driver output with source resistance 0.9-2.0 Ω and sink resistance 0.5-1.2 Ω. |
| 11 | DH | output | High-side MOSFET gate driver output with source resistance 1.6-3.0 Ω and sink resistance 0.6-1.5 Ω. |
| 12 | SW | bidirectional | Switching node return and RDS(on) current sense (-) input; voltage range -5V to 30V. |
| 13 | BST | power_in | Bootstrap voltage input for high-side gate driver; absolute maximum -0.3V to 36V. |
| 14 | EN | input | Enable control input with 100-ns debounce; VIH 1.8V, VIL 0.5V, hysteresis 0.25V. |
| 15 | MODE | input | Mode and frequency selection via resistor-to-GND divider with 16.7-µA source current. |
| 16 | PGOOD | tri_state | Open-drain power-good comparator output; indicates when output voltage within ±8% (typ) of target. |
| 17 | Thermal Pad | passive | Thermal pad for heat dissipation; connect directly to system ground plane with multiple vias. |
