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 fi ltering capacitance and inductance requirements.

FEATURES
■ 2-Phase Operation Reduces Required Input and Output Capacitance
■ Programmable Switching Frequency: 150kHz to 500kHz
■ 6V to 40V Input Range
■ 10V Gate Drive with VCC ≥13V
■ High Current Gate Drive (4A)
■ Programmable Soft-Start and Current Limit
■ Programmable Slope Compensation for High Noise Immunity
■ MOSFET Gate Signals with Programmable Falling Edge Delay for External Synchronous Drivers
■ Programmable Undervoltage Lockout
■ Programmable Duty Cycle Clamp (50% or Higher)
■ Thermally Enhanced 28-Lead TSSOP and 4mm × 5mm QFN Packages

APPLICATIONS
■ Industrial Equipment
■ Telecom Infrastructure
■ Interleaved Isolated Power Supply
