LT3782AEFE#PBF

开关稳压器 2-Phase Step-Up DC/DC Controller

The is a 2-phase current-mode step-up DC/DC Converter Controller features 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, it provides synchronous gate signals with programmable falling edge delay to avoid cross conduction when using external MOSFET drivers. Other features include programmable under voltage lockout, soft-start, current limit, duty cycle clamp 50% or higher and slope compensation.
