LTC3406A

1.5MHz, 600mA

Synchronous Step-Down

Regulator in ThinSOT

DESCRIPTION

The LTC^®3406A is a high efﬁciency monolithic synchro-

nous buck regulator using a constant frequency, current

modearchitecture.Supplycurrentduringoperationisonly

20μA, dropping to ≤1μA in shutdown. The 2.5V to 5.5V

input voltage range makes the LTC3406A ideally suited

forsingleLi-Ionbattery-poweredapplications. 100%duty

cycle provides low dropout operation, extending battery

runtime portable systems. Automatic Burst Mode opera-

tion increases efﬁciency at light loads, further extending

battery runtime.

FEATURES

■

High Efﬁciency: Up to 96%

■

Very Low Quiescent Current: Only 20µA

Low Output Ripple Voltage During Burst Mode^®

■

Operation

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

■

2% 0.6V Reference

■

Shutdown Mode Draw ≤1µA Supply Current

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 LTC3406A is available in

a low proﬁle (1mm) ThinSOT package.

Internal Soft-Start Limits Inrush Current

■

Current Mode Operation for Excellent Line and

Load Transient Response
