DESCRIPTION  
The TK65015 Low Power Step-Up DC-DC converter is  
designed for portable battery powered systems, capable of  
operating from a single battery cell down to 0.9 V.

the "bursting" and skipping of pulses which can be seen at  
the IND pin of the IC.  
The output voltage is laser-trimmed to 3.0 V. An internal  
detector monitors the output voltage and provides an  
active-low microprocessor reset signal whenever the out-  
put voltage falls below an internally preset limit. An internal  
undervoltage lockout circuit is utilized to prevent the induc-  
tor switch from remaining in the "ON" mode when the  
battery voltage is too low to permit normal operation.  
Special care has been taken to achieve high reliability  
through the use of Oxide, Nitride passivation and an  
additional polyimide coating. The TK65015 is available in a  
very small plastic surface mount package. (SOT-23L)  
Pulse burst modulation (PBM) is used to regulate the  
The TK65015 provides the power switch and the control  
circuit for a boost converter. The converter takes a DC  
input (typically a single battery cell) and boosts it up to 3  
volts. Thisregulated3voltoutputistypicallyusedtosupply
