LTC3787
PolyPhase Synchronous
Boost Controller
FEATURES DESCRIPTION n The LTCВ®3787 is a high performance PolyPhaseВ® single
output synchronous boost converter controller that drives
two N-channel power MOSFET stages out-of-phase.
Multiphase operation reduces input and output capacitor
requirements and allows the use of smaller inductors than
the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses and eases thermal
requirements, enabling high power boost applications. n 2-Phase Operation Reduces Required Input and
Output Capacitance and Power Supply Induced Noise
Synchronous Operation for Highest Efficiency and
Reduced Heat Dissipation
Wide VIN Range: 4.5V to 38V (40V Abs Max) and
Operates Down to 2.5V After Start-Up
Output Voltage Up to 60V
В±1% 1.200V Reference Voltage
RSENSE or Inductor DCR Current Sensing
100% Duty Cycle Capability for Synchronous MOSFET
Low Quiescent Current: 135ОјA
Phase-Lockable Frequency (75kHz to 850kHz)
Programmable Fixed Frequency (50kHz to 900kHz)
Power Good Output Voltage Monitor …
