DESCRIPTIO  
FEATURES  
The LT®1767 is a 1.25MHz monolithic buck switching  
regulator. Ahighefficiency1.5A, 0.22switchisincluded  
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.  
1.5A Switch in a Small MSOP Package  
Constant 1.25MHz Switching Frequency  
High Power Exposed Pad (MS8E) Package  
Wide Operating Voltage Range: 3V to 25V  
High Efficiency 0.22Switch  
1.2V Feedback Reference Voltage  
Fixed Output Voltages of 1.8V, 2.5V, 3.3V, 5V  
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 im-  
proves efficiency, especially at lower output currents.  
Shutdown reduces quiescent current to 6µA. Maximum  
switch current remains constant at all duty cycles. Syn-  
chronization allows an external logic level signal to in-  
crease the internal oscillator from 1.4MHz to 2MHz.  
2% Overall Output Tolerance  
Uses Low Profile Surface Mount Components  
Low Shutdown Current: 6µA  
Synchronizable to 2MHz  
Current Mode Loop Control  
Constant Maximum Switch Current Rating at All Duty

TheLT1767isavailableinan8-pinMSOPfusedleadframe  
package and a low thermal resistance exposed pad pack-  
age. Full cycle-by-cycle short-circuit protection and ther-  
mal shutdown are provided. High frequency operation  
allows the reduction of input and output filtering compo-  
nents and permits the use of chip inductors.
