DESCRIPTION
1.5MHz, 600mA
Synchronous Step-Down
Regulator in ThinSOT
The LTC3406AB is a high efciency monolithic synchro-
nous buck regulator using a constant frequency, current
mode architecture. Supply current with no load is 200μA,
dropping to <1μA in shutdown. The 2.5V to 5.5V input
voltage range makes the LTC3406AB ideally suited for
single Li-Ion battery-powered applications. 100% duty
cycle provides low dropout operation, extending battery
run time in portable systems. PWM pulse skipping mode
operation provides very low output ripple voltage for noise
sensitive applications. Refer to LTC3406A for applications
that require Burst Mode operation.
Switching frequency is internally set at 1.5MHz, allowing
the use of small surface mount inductors and capacitors.
The internal synchronous switch increases efciency
and eliminates the need for an external Schottky diode.
Low output voltages are easily supported with the 0.6V
feedback reference voltage. The LTC3406AB is available
in a low prole (1mm) ThinSOT package.
