LTC3896IFE#PBF

LTC®3896 is a high-performance inverting DC/DC switching regulator controller that drives an all-N-channel synchronous power MOSFET stage. It converts a wide-ranging 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– . This contains true ground-referenced RUN, PLLIN and PGOOD pins, eliminating the need for external discrete level-shifting components to interface with the LTC3896. Application includes automotive and industrial power systems, telecommunications power supplies, distributed power systems.

• Ground-referenced control / interface pins
• Integrated bootstrap diode
• Selectable gate drive UVLO thresholds
• Adjustable burst clamp and current limit
• Input supply operating voltage range from 4 to 140V (DRVUV = VOUT, TA = 25°C)
• Typical feedback current is –0.006µA (SENSE– <lt/> VINTVCC – 0.5V, TA = 25°C)
• Power good output voltage monitor
• Programmable input overvoltage lockout
• 38-lead plastic TSSOP package
• Temperature rating range from -40°C to 125°C
