WD3168
5V/300mA Charge Pump Device
WD3168
Http//:www.sh-willsemi.com
Descriptions
The WD3168 is a switched capacitor voltage converter
which produces a regulated, low noise, and low-ripple
output voltage (5V) from an unregulated input voltage.
It maintains 5V regulation even when VIN is greater
than 5V. The 5V output can supply a maximum of
300mA current with a small package.
WD3168 operates in skip-mode when the load current
falls below 4mA under typical condition. In skip-mode
operation, quiescent current is reduced to 170uA.Only
3 external capacitors are needed to generate output
voltage, thereby saving PCB space. Inrush current is
limited by the soft start function during power on and
power transient states.
The WD3168 has built-in current limit protection that is
ideal for HDMI, USB OTG and other battery powered
applications. The WD3168 is available in Green
SOT-23-6L package and is specified over an ambient
temperature range of -40℃ to +85℃.
