LT3782 2-Phase Step-Up DC/DC Controller FEATURES ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTIO ■ ■ ■ 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 SSOP Package 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 (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 SSOP package. , LTC and LT are registered trademarks of Linear Technology Corporation.
