DESCRIPTION  
FEATURES  
Adjustable/Selectable 3V, 3.3V or 5V  
The LTC®1515, LTC1515-3/5 and LTC1515-3.3/5 are  
micropower switched capacitor DC/DC converters that  
produce a regulated output voltage by either stepping up  
or stepping down the input voltage. Output voltage is  
adjustable using an external resistor divider (LTC1515) or  
programmable to either 3V/5V (LTC1515-3/5) or 3.3V/5V  
(LTC1515-3.3/5) using a logic pin.  
Output Voltages  
2V to 10V Input Voltage Range  
Up to 50mA Output Current  
Only Three External Capacitors Required  
Soft Start Limits Inrush Current at Turn-On  
Low Operating Current: 60µA  
Very Low Shutdown Current: < 1µA  
A unique architecture allows the parts to accommodate a  
wide input voltage range (2V to 10V) while maintaining  
±4% regulation. Additional circuitry prevents excessive  
inrush current and output voltage ripple when large VIN to  
VOUT differentials are present.  
Shutdown Disconnects Load from VIN  
VOUT Programmable to 3V/5V or 3.3V/5V  
Short-Circuit and Overtemperature Protected  
650kHz Switching Frequency  
Open-Drain Power-On Reset Output  
Daisy-Chained Control Outputs  
An internal power-on reset circuit forces the POR pin low  
on initial power-up. The POR output remains low until  
200ms (typ) after VOUT is in regulation.  
Available in SO-8 Package  
U
APPLICATIONS  
Thepartsareshort-circuitandovertemperatureprotected.  
Battery life is maximized by very low operating currents  
(ICC = 60µA typ, ICC < 1µA in shutdown). All three parts are  
available in an SO-8 package.
