LT3782

2-Phase Step-UP

DC/DC Controller

DESCRIPTION

The LT

3782 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 (V

≥13V) and 4A peak drive current,

the LT3782 can drive most industrial grade high power

MOSFETs with high efﬁciency. For synchronous applica-

tions, the LT3782 provides synchronous gate signals with

programmable falling edge delay to avoid cross conduc-

tion 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 thermally enhanced 28-lead

TSSOP and 4mm

5mm QFN packages.

For new designs use the LT3782A which has improved

phase matching
