The LTC3104 is a high efficiency, monolithic synchronous step-down converter using a current mode architecture capable of supplying 300mA of output current. The LTC3104 includes an integrated, adjustable 10mA LDO to power noise sensitive functions.

The LTC3104 offers two operational modes: automatic Burst Mode operation and forced continuous mode allowing the user 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 2.6μA, maximizing the efficiency for light loads. Selection of forced continuous mode provides very low noise constant frequency, 1.2MHz operation.

Additionally, the LTC3104 includes an accurate RUN comparator, thermal overload protection, a power good output and an integrated soft-start feature to guarantee that the power system start-up is well controlled.

Applications

  • Remote Sensor Networks
  • Distributed Power Systems
  • Multicell Battery or SuperCap Regulator
  • Energy Harvesters
  • Portable Instruments
  • Low Power Wireless Systems

Product Detail

Demonstration Circuit 1754A features the LTC3104, a high efficiency, monolithic synchronous step-down converter using a current mode architecture capable of supplying 300mA of output current. The IC operates with a fixed frequency oscillator at 1.2MHz. The LTC3104 also incorporates a programmable LDO which can be operated from VIN, VOUT or an independent supply. The LDO can also be independently turned off or on.


The LTC3104 operates with a 2.5V to 15V input voltage range. The demo board has been designed with the main output set to 3.3V and the LDO output (VLDO) to 1.8V.
