Product Summary
The LM2698MM-ADJ is a general purpose PWM boost converter. The 1.9A, 18V, 0.2ohm internal switch enables the LM2698 to provide efficient power conversion to outputs ranging from 2.2V to 17V. The LM2698MM-ADJ can operate with input voltages as low as 2.2V and as high as 12V. Current-mode architecture provides superior line and load regulation and simple frequency compensation over the device’s 2.2V to 12V input voltage range. The LM2698MM-ADJ sets the standard in power density and is capable of supplying 12V at 400mA from a 5V input. The applicaitons of the LM2698MM-ADJ are 3.3V to 5V, 5V to 12V conversion, Distributed Power, Set-Top Boxes, DSL Modems, Diagnostic Medical Instrumentation, Boost Converters, Flyback Converters and SEPIC Converters.
