DESCRIPTION
The LTC®3788-1 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.

FEATURES
■ Synchronous Operation for Highest Effi ciency and Reduced Heat Dissipation
■ Wide Input Range: 4.5V to 38V (40V Abs Max) and Operates Down to 2.5V After Start-Up
■ Output Voltages Up to 60V
■ ±1% 1.2V Reference Voltage
■ RSENSE or Inductor DCR Current Sensing
■ 100% Duty Cycle Capability for Synchronous MOSFET
■ Low Quiescent Current: 125μA
■ Phase-Lockable Frequency (75kHz to 850kHz)
■ Programmable Fixed Frequency (50kHz to 900kHz)
■ Adjustable Output Voltage Soft-Start
■ Power Good Output Voltage Monitor
■ Low Shutdown Current IQ: <8μA
■ Internal LDO Powers Gate Drive from VBIAS or EXTVCC
■ Available in a Narrow SSOP Package

APPLICATIONS
■ Industrial
■ Automotive
■ Medical
■ Military
