Product Overview

The LTC3863MPMSE#PBF is a robust inverting DC/DC PMOS Controller drives a P-channel power MOSFET to generate a negative output and requires just a single inductor to complete the circuit. Output voltages from -0.4 to -150V are typically achievable with higher voltages possible, only limited by external components. It offers excellent light load efficiency, drawing only 70µA 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. The LTC3863 offers programmable soft-start or output tracking. Safety features include overvoltage, overcurrent and short-circuit protection including frequency foldback.
  • 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
  • 7µA Low shutdown
