Demonstration circuit 2119A features the LTC®3115-2, a high voltage monolithic synchronous buck-boost converter optimized for applications with fast input voltage transients. The DC2119A demo board has two user selectable operating modes: Burst Mode© and Forced Continuous Operation (Fixed Frequency PWM) (JP1). There is also an accurate programmable RUN pin which is used to ENABLE the converter (JP2). The DC2119A operates with a 2.7V to 40V input voltage range. The demo board has been designed with the output voltage set to 5.0V. The LTC3115-2 incorporates a proprietary low noise switching algorithm which optimizes efficiency with input voltages above, below or equal to the output voltage and ensures seamless transitions between operating modes. The demo board has been programmed to operate at 750kHz in PWM mode to optimize small size with high efficiency operation. The demo board also has optional provisions to backfeed VCC in order to increase efficiency in some 5V output applications. There is also a provision for an optional Schottky diode from SW2 to VOUT for applications where VOUT is greater than 20V and short-circuit protection is desired. Consult the data sheet for more information on these options. Figures 1 and 2 show typical demo board efficiency. Figure 3 shows the response to an input voltage step. The LTC3115-2 data sheet has detailed information about the operation, specifications, and applications of the part. The data sheet should be read in conjunction with this Quick Start Guide.
