The recommended layout and placement for the LTC2655BCGN-L16#PBF can be found in the Linear Technology application note AN140, which provides guidelines for PCB layout, component placement, and thermal management to ensure optimal performance and reliability.
The LTC2655BCGN-L16#PBF has a programmable output voltage range from 0.5V to 5.25V. To select the correct output voltage range, consider the voltage requirements of your load, the input voltage range, and the desired output voltage accuracy. Refer to the datasheet's output voltage range selection table to determine the correct resistor values for your application.
The maximum output current capability of the LTC2655BCGN-L16#PBF is 50mA per channel. However, the actual output current capability may be limited by the thermal performance of the device, the input voltage, and the output voltage. Refer to the datasheet's electrical characteristics table for more information.
To ensure accurate output voltage regulation, follow the datasheet's guidelines for output voltage setting, input voltage range, and output capacitor selection. Additionally, consider the effects of temperature, input voltage, and output current on output voltage accuracy. Use the datasheet's output voltage accuracy equation to calculate the expected output voltage accuracy for your application.
The Power Good (PG) output pin on the LTC2655BCGN-L16#PBF is an open-drain output that indicates when the output voltage is within 10% of its programmed value. The PG pin can be used to monitor the output voltage and provide a signal to other devices in the system when the output voltage is valid.
