LTC3103

1.8µA Quiescent Current,

15V, 300mA Synchronous

Step-Down DC/DC

Converter

FEATURES

DESCRIPTION

The LTC^®3103 is a high efficiency, monolithic synchro-

nous step-down converter using a current mode archi-

tecture capable of supplying 300mA of output current.

Ultralow Quiescent Current: 1.8µA

Synchronous Rectification: Efficiency Up to 95%

Wide V Range: 2.5V to 15V

Wide V

Range: 0.6V to 13.8V

OUT

The LTC3103 offers two operational modes: automatic

Burst Mode operation and forced continuous mode allow-

ing the user the ability to optimize output voltage ripple,

noise and light load efficiency. With Burst Mode operation

enabled, the typical DC input supply current at no load

drops to 1.8µA maximizing the efficiency for light loads.

Selection of forced continuous mode provides very low

noise constant frequency, 1.2MHz operation.

300mA Output Current

User-Selectable Automatic Burst Mode^®or Forced

Continuous Operation

Accurate and Programmable RUN Pin Threshold

1.2MHz Fixed Frequency PWM

Internal Compensation

Power Good Status Output for V

OUT

Available in Thermally Enhanced 3mm × 3mm ×

0.75mm, 10-Pin DFN and 10-Pin MSOP Packages

Additionally, the LTC3103 includes an accurate RUN com-

parator, thermal overload protection, a power good output

and an integrated soft-start feature to guarantee that the

power system start-up is well controlled.
