CXSD6186

To ensure the longest battery life in portable applications, the CXSD6186 provides a power-saving pulse -Skipping Modulation (PSM) mode to reduce quiescent current under light load operation to save power. The CXSD6186 supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH cell, USB, and other standard power sources

二.产品概述a3b嘉泰姆


     The CXSD6186 is a step-down current-mode, DC-DC converter. At heavy load, the constant-frequency PWM control performs excellent stability and transient response. To ensure the longest battery life in portable applications, the CXSD6186 provides a power-saving pulse -Skipping Modulation (PSM) mode to reduce quiescent current under light load operation to save power. The CXSD6186 supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH cell, USB, and other standard power sources. The output voltage is adjustable from 0.6V to the input voltage, while the part number suffix CXSD6186 indicates pre-set output voltage of 3.3V, 2.8V, 2.5V, 1.8V, 1.5V, 1.2V or adjustable. All versions employ internal power switch and synchronous rectifier for to minimize external part count and realize high efficiency. During shutdown, the input is disconnected from the output and the shutdown current is less than 0.1μA. Other key features include under-voltage lockout to prevent deep battery discharge.  a3b嘉泰姆
