LTC3406AB

1.5MHz, 600mA

Synchronous Step-Down

Regulator in ThinSOT

DESCRIPTION

The LTC^®3406AB is a high efﬁciency 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

operationprovidesverylowoutputripplevoltagefornoise

sensitive applications. Refer to LTC3406A for applications

that require Burst Mode^®operation.

FEATURES

■

High Efﬁciency: Up to 96%

■

600mA Output Current

■

2.5V to 5.5V Input Voltage Range

■

1.5MHz Constant Frequency Operation

■

No Schottky Diode Required

■

Low Dropout Operation: 100% Duty Cycle

■

Low Quiescent Current: 200μA

2% 0.6V Reference

■

Shutdown Mode Draws <1μA Supply Current

■

Internal Soft-Start Limits Inrush Current

■

Current Mode Operation for Excellent Line and

Load Transient Response

Switching frequency is internally set at 1.5MHz, allowing

the use of small surface mount inductors and capacitors.

The internal synchronous switch increases efﬁciency

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 proﬁle (1mm) ThinSOT package.
