The Analog Devices Inc. DC2815A Demonstration Board includes a pre-mounted LT3120 in an LQFN-24 package.
The DC2815A demo board has four user-selectable operating modes:
- An accurate programmable EN/UVLO pin is used to ENABLE the converter (JP1).
- Programmable MPPC (Maximum Power Point Control) for input regulation setpoint (JP2).
- Burst Mode® operation and external CLK/Fixed Frequency PWM (JP3).
- Programmable Output Average Current Limit setpoint (JP4).
The LT3120 uses average current mode control to simplify voltage loop compensation and provide good line and load transient response.
The DC2815A operates with a 2.5V to 26V input voltage range. The Demo Board has been designed with the output voltage set to 5V. The LT3120 incorporates a proprietary low noise switching algorithm that optimizes efficiency with input voltages above, below, or equal to the output voltage and ensures seamless transitions between operating modes.
