The LTC ? 3601 is a high ef?ciency, monolithic synchronous
buck regulator using a phase-lockable controlled on-time,
current mode architecture capable of supplying up to 1.5A
of output current. The operating supply voltage range is
from 4V to 15V, making it suitable for a wide range of
power supply applications.
The operating frequency is programmable from 800kHz to
4MHz with an external resistor enabling the use of small
surface mount inductors. For switching noise sensitive
applications, the LTC3601 can be externally synchronized
over the same frequency range. An internal phase-locked
loop aligns the on-time of the top power MOSFET to the
internal or external clock. This unique constant frequency/
controlled on-time architecture is ideal for high step-down
ratio applications that demand high switching frequencies
and fast transient response.

TYPICAL APPLICATION
The LTC3601 offers two operational modes: Burst Mode
operation and forced continuous mode to allow the user
to optimize output voltage ripple, noise, and light load
ef?ciency for a given application. Maximum light load
ef?ciency is achieved with the selection of Burst Mode
operation while forced continuous mode provides minimum
output ripple and constant frequency operation.
