National's new LM315x SIMPLE SWITCHER family features:

  • Few external components to reduce overall solution size and complexity
  • Constant-On-Time (COT) architecture eliminates the need for compensation circuitry and provides a fixed frequency
  • Synchronous architecture delivers efficiencies up to 93%
  • Up to 12A of output current. Switching
  • Frequency up to 1 MHz
  • Wide input voltage range from 6V to 42V
  • Patent-pending Emulated Ripple Mode circuitry allows use of low ESR output capacitors

National's new WEBENCH Power Designer online tool lets you design and simulate your design in minutes and includes FET and passive external component selection and electrical as well as thermal simulation.
