LTC3410-1.875

2.25MHz, 300mA

Synchronous Step-Down

Regulator in SC70

DESCRIPTIO

FEATURES

■

High Efficiency: Up to 93%

The LTC^®3410-1.875 is a high efficiency monolithic syn-

chronous buck regulator using a constant frequency,

current mode architecture. Supply current during opera-

tionisonly26µA, droppingto<1µAinshutdown. The2.5V

to 5.5V input voltage range makes the LTC3410-1.875

ideally suited for single Li-Ion battery-powered applica-

tions. 100% duty cycle provides low dropout operation,

extending battery life in portable systems.

■

Very Low Quiescent Current: Only 26µA

■

Low Output Voltage Ripple

■

300mA Output Current at V_IN= 3V

■

380mA Minimum Peak Switch Current

2.5V to 5.5V Input Voltage Range

2.25MHz Constant Frequency Operation

No Schottky Diode Required

■

Stable with Ceramic Capacitors

Shutdown Mode Draws <1µA Supply Current

±2% Output Voltage Accuracy

Current Mode Operation for Excellent Line and

Load Transient Response

Overtemperature Protected

Available in Low Profile SC70 Package

Switching frequency is internally set at 2.25MHz, allowing

the use of small surface mount inductors and capacitors.

The LTC3410-1.875 is specifically designed to work well

with ceramic output capacitors, achieving very low output

voltage ripple and a small PCB footprint.

■

The internal synchronous switch increases efficiency and

eliminates the need for an external Schottky diode. The

LTC3410-1.875 is available in a tiny, low profile SC70

package.
