DC516A - Schematic9/24/2009
Demonstration circuit 516A-B is a low output voltage, synchronous boost converter featuring the LTC3424. The LTC3424 is ideal for applications that require an output voltage between 1.5V to 2.6V from a single alkaline or NiCd/NiMH cell. A bias voltage (VDD) of 2.7V to 5.5V is required to power the internal circuitry. The input voltage (VIN) range is 1V to 1.6V, but once up and running, the device can operate with an input voltage as low as 0.5V. The output voltage is set at 1.8V. For a 1V minimum battery voltage, the LTC3424 can provide 600mA.
