Product Description
- The DC1687A demonstration circuit features LTC3115-1 DC to DC converter. The LTC3115-1 is a high voltage monolithic synchronous buck boost DC to DC converter. The DC1687A demo board has two user selectable operating modes, burst mode operation 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 DC1687A 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 LTC3115-1 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 1MHz in PWM mode to optimize small size with high efficiency operation.
- Synchronizable up to 2MHz with an external clock
- 30µA no load quiescent current in burst mode operation
- Ultralow noise buck boost PWM
- Internal soft start
- 3µA supply current in shutdown
- Programmable input undervoltage lockout
