SLVSCQ7 APRIL 2015  
TPS61046 28-V Output Voltage Boost Converter in WCSP Package  
1 Features  
3 Description  
The TPS61046 is a highly integrated boost converter  
1
Input Voltage Range: 1.8 V to 5.5 V, 1.6 V after  
Startup  
designed for applications requiring high voltage and  
tiny solution size such as PMOLED panel and sensor  
module. The TPS61046 integrates a 30-V power  
switch, input/output isolation switch, and power diode.  
It can output up to 28 V from input of a Li+ battery or  
two cell alkaline batteries in series.  
Output Voltage Up to 28 V  
Integrated Power Diode and Isolation Switch  
900-mA (typical) Switch Current  
Up to 85% Efficiency at 3.6-V Input and 12-V  
Output  
The TPS61046 operates with a switching frequency  
at 1.0 MHz. This allows the use of small external  
components. The TPS61046 has an internal default  
12-V output voltage setting by connecting the FB pin  
to the VIN pin. Thus it only needs three external  
components to get 12-V output voltage. Together with  
WCSP package, the TPS61046 gives a very small  
overall solution size. The TPS61046 has typical 900-  
mA switch current limit. It has 10-ms built-in soft start  
time to minimize the inrush current. When the  
TPS61046 is in shutdown mode, the isolation switch  
disconnects the output from input to minimize the  
leakage current. The TPS61064 also implements  
output short circuit protection, output over-voltage  
protection and thermal shutdown.  
500-nA Ultra-low Shutdown Current  
±2% Output Voltage Accuracy  
Power Save Operation Mode at Light Load  
Internal 10-ms Soft Start Time  
True Disconnection between Input and Output  
during Shutdown  
Output Short Circuit Protection  
Output Over-Voltage Protection  
Thermal Shutdown Protection
