1× and 1.5× Charge Pump  
The TPS60255 is  
a
high-efficiency, constant  
Auto Switching Between 1× and 1.5× Modes  
750 kHz Charge Pump Frequency  
frequency charge pump DC/DC converter that uses  
1× and 1.5× conversion to maximize efficiency for the  
input voltage range. By using adaptive 1×/1.5×  
charge-pump modes and very low dropout current  
regulators, the TPS60255 achieves high efficiency for  
the entire one-cell lithium battery range. The  
protection features include soft start, over-current  
limit, thermal shut down, and over-voltage detection.  
The device automatically detects and removes  
unused current sinks from the control loop.
