DESCRIPTIO  
FEATURES  
The LT®3436 is an 800kHz monolithic boost switching  
regulator. A high efficiency 3A, 0.1switch is included on  
the die together with all the control circuitry required to  
complete a high frequency, current-mode switching regu-  
lator. Current-mode control provides fast transient re-  
sponse and excellent loop stability.  
Constant 800kHz Switching Frequency  
Wide Operating Voltage Range: 3V to 25V  
High Efficiency 0.1/3A Switch  
1.2V Feedback Reference Voltage  
±2% Overall Output Voltage Tolerance  
Uses Low Profile Surface Mount External  
Components  
New design techniques achieve high efficiency at high  
switching frequencies over a wide operating range. A low  
dropout internal regulator maintains consistent perfor-  
manceoverawiderangeofinputsfrom24VsystemstoLi-  
Ion batteries. An operating supply current of 1mA main-  
tains high efficiency, especially at lower output currents.  
Shutdown reduces quiescent current to 11µA. Maximum  
switch current remains constant at all duty cycles. Syn-  
chronizationcapabilityallowsanexternallogiclevelsignal  
to increase the internal oscillator from 1MHz to 1.4MHz.  
Low Shutdown Current: 11µA  
Synchronizable from 1MHz to 1.4MHz  
Current-Mode Control  
Constant Maximum Switch Current Rating  
at All Duty Cycles*  
Available in a Small Thermally Enhanced  
TSSOP-16 Package  
U
APPLICATIO S  
DSL Modems  
Full cycle-by-cycle switch current limit protection and ther-  
mal shutdown are provided. High frequency operation al-  
lows the reduction of input and output filtering components  
and permits the use of tiny chip inductors. The LT3436 is  
available in an exposed pad, 16-pin TSSOP package.
