General Description

The ILC6360 step-up/step-down DC-DC converter is a switch mode converter, capable of supplying up to 500mA output current, at a fixed or user selectable output voltage. The range of input, and output voltage options makes the ILC6360 ideal for Lithium-ion (Li-ion) , or any other battery application, where the input voltage range spans above and below the regulated output voltage. When ILC6360’s input voltage exceeds the output voltage by more than 800mV, the output will begin to track the input linearly.
