说明
- DC1237A-A, Demonstration Circuit for the LTC3527 is a dual output, high-efficiency synchronous boost converter demo boards with each having an 800mA and a 400mA power switch. With a light load, the boost converters can startup with an input voltage as low as 700mV and once started, the input can go as low as 500mV while maintaining a regulated output voltage. Jumpers set the output voltages to one of three options for each output: 3V, 3.3V or 5V for Vout1 and 1.8V, 2.85V or 3.3V for Vout2. The devices can provide 200mA at 3.3V from a 1.5V input
