Wide Input Voltage Range: 3.5V to 30V

Very Few External Parts Required  
Self-Protected Against Overloads  
Available in Standard and Surface Mount  
5-Pin Packages  
The LT1268B and LT1268 are monolithic high power  
switching regulators. Identical to the popular LT1070,  
except for switching frequency (150kHz) and higher  
switch current, they can be operated in all standard  
switching configurations including buck, boost, flyback,  
and inverting. A high current, high efficiency switch is  
included on the die along with all oscillator, control, and  
protection circuitry. Integration of all functions allows  
the LT1268 to be built in standard 5-pin power packages.  
This makes it extremely easy to use and provides “bust  
proof” operations similar to that obtained with 3-pin  
linear regulators.

The LT1268 operate with supply voltages from 3.5V to  
30V and draw only 7mA quiescent current. By utilizing  
current mode switching techniques, it provides excellent  
AC and DC load and line regulation.

USER NOTE:  
This data sheet is only intended to provide specifications, graphs, and a general functional  
description of the LT1268B/LT1268. Application circuits are included to show the capability of the  
LT1268B/LT1268.Acompletedesignmanual(AN19)shouldbeobtainedtoassistindevelopingnew  
designs. This manual contains a comprehensive discussion of both the LT1070 and the external  
components used with it, as well as complete formulas for calculating the values of these  
components. The manual can also be used for the LT1268B/LT1268 factoring in the higher switch  
current rating and higher operating frequency.  
TheLT1268useanadaptiveanti-satswitchdrivetoallow

An externally activated shutdown mode reduces total  
supply current to 100µA typical for standby operation.
