Product Overview

The LTC3864EMSE#PBF is a robust high voltage step-down DC/DC Controller drives a P-channel power MOSFET switch allowing 100% duty cycle operation. The wide input and output voltage ranges cover a multitude of applications. This device has been verified with the failure mode and effects analysis (FMEA) procedure for operation during failure conditions. It offers excellent light load efficiency, drawing only 40µA quiescent current in user programmable Burst Mode operation. Its peak current-mode, constant frequency PWM architecture provides for good control of switching frequency and output current limit. The switching frequency can be programmed from 50 to 850kHz with an external resistor and can be synchronized to an external clock from 75 to 750kHz. It offers programmable soft-start or output tracking. Safety features include overvoltage protection, overcurrent and short-circuit protection including frequency foldback and a power good output signal.
  • Strong high voltage MOSFET gate driver
  • Constant frequency current mode architecture
  • Verified FMEA for adjacent pin open/short
  • Selectable high efficiency burst mode operation or pulse-skipping mode at light loads
  • Accurate current limit
  • Programmable soft-start or voltage tracking
  • Internal soft-start guarantees smooth start-up
  • Power good output voltage monitor
  • 7µA Low shutdown
