Description

General part information

LT3782A Series

The LT3782A is a current mode 2-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 LT3782A can drive most industrial grade high power MOSFETs with high efficiency. For synchronous applications, the LT3782A 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 LT3782A is identical to the LT3782 except that the LT3782A has a tighter current sense mismatch tolerance.The LT3782A is available in thermally enhanced 28-lead TSSOP and 4mm × 5mm QFN packages.ApplicationsIndustrial EquipmentTelecom InfrastructureInterleaved Isolated Power Supply
