The LT3782 is a current mode two phase step-up DC/DC converter controller. Its high switching frequency (up to 500kHz) and 2-phase operation reduce system filtering capacitance and inductance requirements.

With 10V gate drive (VCC ≥13V) and 4A peak drive current, the LT3782 can drive most industrial grade high power MOSFETs with high efficiency. For synchronous applications, the LT3782 provides synchronous gate signals with programmable falling edge delay to avoid cross conduction when using external MOSFET drivers. Other features include programmable undervoltage lockout, soft-start, current limit, duty cycle clamp (50% or higher) and slope compensation.

The LT3782 is available in a thermally enhanced 28-lead TSSOP and 4mm x 5mm QFN packages.

For new designs use the LT3782A which has improved
phase matching
