LT3782EFE#PBF

LT3782 is a current mode two phase step-up DC/DC converter controller. Its high switching frequency (upto 500KHz) and 2-phase operation reduce system filtering capacitance and inductance requirements. For synchronous applications, this device 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. It is widely used in application such as industrial equipment, telecom Infrastructure, interleaved isolated power supply etc.

• Input voltage range is 6V to 40V
