Step-Down Regulator

DESCRIPTIO

FEATURES

■

High Efficiency: Up to 96%

The LTC^®3564 is a high efficiency monolithic synchro-

nous buck regulator using a constant frequency, current

mode architecture. Supply current during operation is

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

5.5VinputvoltagerangemakestheLTC3564ideallysuited

for single Li-Ion battery-powered or 3.3V to 5V input

voltage applications. 100% duty cycle provides low drop-

out operation, extending battery life in portable systems.

Automatic Burst Mode^®operation increases efficiency at

light loads, further extending battery runtime.

■

Very Low Quiescent Current: Only 20μA

■

1.25A Output Current

■

2.5V to 5.5V Input Voltage Range

2.25MHz Constant Frequency Operation

No Schottky Diode Required

■

Low Dropout Operation: 100% Duty Cycle

0.6V Reference Allows Low Output Voltages

Shutdown Mode Draws ≤1μA Supply Current

Current Mode Operation for Excellent Line and

Load Transient Response

Switching frequency is internally set at 2.25MHz, allowing

the use of small surface mount inductors and capacitors.

■

Overtemperature Protected

Low Profile (1mm) ThinSOT^TMand

6-Lead (2mm × 3mm) DFN Packages

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 feed-

back reference voltage. The LTC3564 is available in low

profile (1mm) ThinSOT and 6-Lead (2mm × 3mm) DFN

packages.
