The LTC1266, a synchronous, step-down switching regulator controller that can provide high efficiency at 10mA loads, is described.
Synchronous step-down regulator
The new LTC1266 is a synchronous, step-down switching regulator controller that can drive two external, N-channel MOSFET switches. The superior performance of N-channel MOSFETs enables the LTC1266 to achieve high efficiency at loads of 10A or more with few additional components. Burst Mode operation provides high efficiency at light loads—efficiency is greater than 90% for loads from 10mA to 10A. The ability to provide 10A at high efficiency is critical for supplying ...
