LTC3601 monolithic synchronous buck regulator

LTC3601 from Linear Technology is an monolithic synchronous buck regulator using a phase-lockable controlled on-time, capable of supplying up to 1.5A of output current.
The LTC3601 operating supply voltage range is from 4V to 15V making it suitable for a wide range of power supply applications.

The operating frequency of the LTC3601 buck regulator is programmable from 800kHz to 4MHz with an external resistor enabling the use of small surface mount inductors.
The LTC3601 buck regulator can operate in two modes: Burst Mode operation and forced continuous mode to allow the user to optimize output voltage ripple, noise, and light load efficiency for a given application.
Main features of this regulator are : 4V to 15V Input Voltage Range , 1.5A Output Current , Up to 96% Efficiency , Very Low Duty Cycle Operation, Adjustable Switching Frequency: 800kHz to 4MHz , User Selectable Burst Mode or Forced Continuous Operation , Short-Circuit Protected , Output Voltage Tracking Capability , Programmable Soft-Start .
