Introduction

AI Translation

The LTC3788 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 LTC3788 to be used in high power boost applications. A constant-frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3788 features a precision 1.2V reference and dual power good output indicators. A 4.5V to 38V input supply range encompasses a wide range of system architectures and battery chemistries. 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.
