LTC3788EGN-1#PBF

LTC3788-1 is a high performance 2-phase dual synchronous boost converter controller that drives all N-channel power MOSFETs. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the device to be used in high power boost applications. A constant-frequency current mode architecture allows a phase-lockable frequency of upto 850KHz. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. It features a precision 1.2V reference and a power good output indicator. Independent SS pins for each controller ramp the output voltages during start-up. The PLLIN/MODE pin selects among Burst Mode operation, pulse-skipping mode or continuous inductor current mode at light loads. It is widely used in applications such as industrial, automotive, medical, military etc.
