Product Details

Demo Circuit 1402 is a Highly Integrated 6-Channel Portable PMIC featuring the LTC3577 (DC1402A-A) and the LTC3577-1 (DC1402A-B), which include a push button controller, two 150mA LDOs, three synchronous buck converters (800mA, 500mA, 500mA), a Li-Ion battery charger, a Power-Path controller, and high voltage buck controller interface that allows the board to control a separate LTC high voltage buck converter demo board to drive an LED (included with the demo board). The LTC3577's battery charger has a 4.2V float voltage while the LTC3577-1 has a 4.1V float voltage. The board can be power with a 1.6V to 5.5V DC input supply, a USB input or a 5V wall adapter. Do not look directly at the operating LED as this circuit produces light that can damage eyes.
