LTC3200/LTC3200-5  
Low Noise, Regulated  
Charge Pump DC/DC Converters  
U
FEATURES  
DESCRIPTIO  
The LTC®3200/LTC3200-5 are low noise, constant fre-  
quency switched capacitor voltage doublers. They pro-  
duce a regulated output voltage from a 2.7V to 4.5V input  
with up to 100mA of output current. Low external parts  
count (one flying capacitor and two small bypass capaci-  
tors at VIN and VOUT) make the LTC3200/LTC3200-5  
ideally suited for small, battery-powered applications.  
Low Noise Constant Frequency Operation  
Output Current: 100mA  
Available in 8-Pin MSOP (LTC3200) and Low  
Profile (1mm) 6-Pin ThinSOTTM (LTC3200-5)  
Packages  
2MHz Switching Frequency  
Fixed 5V ± 4% Output (LTC3200-5) or ADJ  
VIN Range: 2.7V to 4.5V  
Automatic Soft-Start Reduces Inrush Current  
No Inductors  
ICC <1µA in Shutdown  
A new charge-pump architecture maintains constant  
switching frequency to zero load and reduces both output  
and input ripple. The LTC3200/LTC3200-5 have thermal  
shutdown capability and can survive a continuous short-  
circuit from VOUT to GND. Built-in soft-start circuitry  
prevents excessive inrush current during start-up.

the load from VIN and reduces quiescent current to <1µA.
