The LTC

®3604 is a high efﬁciency, monolithic synchronous

buck regulator using a phase-lockable controlled on-time,

current mode architecture capable of supplying up to 2.5A

of output current. The operating supply voltage range is

from 3.6V 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 LTC3604 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.

The LTC3604 offers two operational 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. Maximum light load

efﬁciency is achieved with the selection of Burst Mode

operationwhileforcedcontinuousmodeprovidesminimum

output ripple and constant frequency operation.
