Analog Devices Inc. LTC3124 Demo Board DC1859A

Analog Devices Inc. LTC3124 Demo Board DC1859A is an evaluation board featuring a DC-DC boost converter example circuit based on the LTC3124 Dual-Phase Synchronous Step-Up DC-DC Converter. The LTC3124 Demo Board DC1859A operates over 1.8V to 5.5V input and generates 12V at 1.5A output from a 5V input. The LTC3124 has a 2% precise voltage reference, which can generate an output voltage with 2.2% tolerance when 0.1% voltage divider resistors are used. The 1MHz switching frequency operation results in a small and efficient circuit. The LTC3124 Converter operates with only one phase in burst mode and achieves over 90% efficiency with a 100mA load. The DC1859A Board can be easily modified to generate different output voltages.

The LTC3124 Demo Board DC1859A has a small circuit footprint. It is a high-performance and cost-effective solution for generating outputĀ voltages up to 15V from inputs as low as 1.8V.
