The 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 LTC3788-1 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 LTC3788-1 features a precision 1.2V reference and a power good output indicator. 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.
For a leadless 32-pin QFN package with additional features of adjustable current limit, clock out, phase modulation and two PGOOD outputs, see the LTC3788 data sheet.
