Description
3A, 4MHz, Monolithic
Synchronous
Step-Down Regulator
The LTC3412A is a high efficiency monolithic synchro-
nous, step-down DC/DC converter utilizing a constant
frequency, current mode architecture. It operates from
an input voltage range of 2.25V to 5.5V and provides a
regulated output voltage from 0.8V to 5V while deliver-
ing up to 3A of output current. The internal synchronous
powerswitchwith77mΩon-resistanceincreasesefficiency
and eliminates the need for an external Schottky diode.
Switching frequency is set by an external resistor or can
be synchronized to an external clock. 100% duty cycle
provides low dropout operation extending battery life in
portable systems. OPTI-LOOP compensation allows the
transient response to be optimized over a wide range of
loads and output capacitors.
The LTC3412A can be configured for either Burst Mode
operation or forced continuous operation. Forced continu-
ous operation reduces noise and RF interference while
BurstModeoperationprovideshighefficiencybyreducing
gate charge losses at light loads. In Burst Mode operation,
external control of the burst clamp level allows the output
voltage ripple to be adjusted according to the application
requirements.
