LTC3896EFE#PBF (LINEAR TECHNOLOGY)

The LTC3896EFE#PBF is a 150V low IQ, synchronous inverting DC/DC controller in 38 pin TSSOP package. This 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. It contains true ground-referenced RUN, PLLIN and PGOOD pins, eliminating the need for external discrete level shifting components to interface with the IC. 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. The OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. It is used in telecommunications power supplies and distributed power systems.
