Analog Devices Inc. LTC3129 Demo Board DC1922A

Analog Devices Inc. LTC3129 Demo Board DC1922A is an evaluation board featuring an example circuit based on the LTC3129 200mA Buck-Boost DC-DC Converter. The LTC3129 Demo Board DC1922A has two user-selectable operating modes: Burst Mode® Operation and Fixed Frequency Pulse Width Modulation (PWM). There is also an accurate programmable RUN pin that is used to enable the Converter. The LTC3129 also incorporates a maximum power point control function, which can be enabled for applications where the input source is a solar cell or is high impedance, such as intrinsically safe applications or high ZOUT Thermal Electric Generators (TEGs).

The LTC3129 Demo Board DC1922A operates with a 2.42V to 15V input voltage range and has been designed with the output voltage set to 5.0V. Once the converter is started, the LTC3129 can operate with VIN as low as 1.92V provided VCC is backfed. The DC1922A Board has optional provisions to backfeed VCC in order to increase efficiency in some 5V output applications or to allow operation with VIN down to 1.92V.


  • Input Voltage Range (VIN): 2.42V to 15V
  • Output Voltage (VOUT): 5.0V
  • Output Current (IOUT1): 200mA, for VIN > VOUT
