Cxsd6187 is a buck current DC-DC converter. In heavy load, frequency PWM control performs well in stability and transient response. To ensure the longest battery life in portable applications, the cxsd6187 provides power saving Pulse Skip Modulation (PSM) mode to reduce the operation of light static current load to save power. The cxsd6187 supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single lithium-ion cell, multiple alkaline / NiMH batteries, USB and other standard power supplies. The output voltage can be adjusted from the input voltage of 0.6V, while the part number suffix cxsd6187-xx shows the preset output voltage of. 3V, 2.8V, 2.5V, 1.8V, 1.5V, 1.2V or adjustable. All versions use internal power switches and synchronous rectifiers to reduce external counts and achieve high efficiency. During shutdown, the input and output and current are less than 0.1 μ a. Other key features include undervoltage locking to prevent deep battery discharge
