General Description
The G5910 Charge-Pump is a switched-capacitor
voltage converter that delivers a regulated output. The
external inductor is not required for operation. Using
small capacitors, the G5910 can deliver up to 90mA
(@VIN=3V) to the voltage-regulated output. The G5910
features high efficiency over a large portion of its load
range making this device ideal for battery-powered
applications. The combination of few external compo-
nents and small package size keeps the total con-
verter board area to a minimum in space-restricted
applications. The G5910 contains a thermal manage-
ment circuit to protect the device under continuous
output short circuit conditions.
The G5910 is available in a surface mount SOT-23-6
and TSOT-23-6 package.
