PRODUCTION DATA
The drivers for the external high-side and low-side MOSFETs are capable of driving a gate-to-source voltage, VBP. The LDRV driver for the low-side MOSFET switches between VBP and PGND, while the HDRV driver for the high-side MOSFET is referenced to SW and switches between BOOT and SW. The drivers have non-overlapping timing that is governed by an adaptive delay circuit to minimize body diode conduction in the synchronous rectifier.
