LTC3896EFE 产品详情

The LTC3896EFE#TRPBF is a high performance inverting DC/DC switching regulator controller that drives an all N-channel synchronous power MOSFET stage. It converts a wideranging positive input voltage source to a regulated negative output that can be as much as 60V below ground. The input can operate from a voltage as low as 4V and as high as 140V – |VOUT–|.

The LTC3896EFE#TRPBF contains true ground-referenced RUN, PLLIN and PGOOD pins, eliminating the need for external discrete level-shifting components to interface with the LTC3896.

A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. The low 40μA no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3896EFE#TRPBF features a precision 0.8V reference and power good output indicator. The soft-start (SS) pin ramps the output voltage during start-up.

Feature

  • Integrated Bootstrap Diode
  • Low Operating IQ: 40μA (Shutdown = 10μA)
  • Selectable Gate Drive UVLO Thresholds
  • Onboard LDO or External NMOS LDO for DRVCC
  • EXTVCC LDO Powers Drivers from Output
  • Phase-Lockable Frequency (75kHz to 850kHz)
  • Programmable Fixed Frequency (50kHz to 900kHz)
  • Selectable Continuous, Pulse-Skipping or Low Ripple Burst Mode® Operation at Light Loads
  • Adjustable Burst Clamp and Current Limit
  • Power Good Output Voltage Monitor
  • Programmable Input Overvoltage Lockout
  • 38-Lead TSSOP High Voltage Package

Applications

  • Automotive and Industrial Power Systems
  • Telecommunications Power Supplies
  • Distributed Power Systems
