LT1619 - Low Voltage Current Mode PWM Controller
The LT®3782 is a two-phase boost DC/DC current mode conversion controller. Its high switching frequency (up to 500kHz) and two-phase operation reduce system filter capacitance and inductance requirements. With a gate driver of 10V (VCC≥13V) and a peak drive current of 4A, the LT3782 can drive industrial-grade high-power and high-efficiency MOSFETs. For synchronous applications, the LT3782 provides a programmable falling edge delay of the synchronous gate signal 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.
