- Integrated VOUT Discharge
- 200kHz, 300kHz, 400kHz, or 600kHz Selectable fSW
- Forced Continuous Conduction Mode (FCCM)
- Configurable VIN Under-Voltage Lockout (UVLO) Hysteresis
Applications
- USB Power Delivery (PD)
Design Notes
- Buck-boost operation keeps the output regulated either side of the input, which costs efficiency compared with a pure buck at the same rating.
- Power switches are integrated, so the thermal path is the PCB copper under the pad.
- Package QFN-32 — check the land pattern in the datasheet before layout.
