Features

for optimal transient response to load apply and removal. One of these features is highly accurate, fully differential, continuous DCR current sensing for load line programming and channel current balance. Active Pulse Positioning (APP) modulation is another unique feature, allowing for quicker initial response to high di/dt load transients. This controller also allows the user the flexibility to choose between PHASE detect or LGATE detect adaptive dead time schemes. This ability allows the ISL6322 to be used in a multitude of applications where either scheme is required. Protection features o.
