Product Highlight

  • Type: DC/DC Converters
  • Core Supported: SP7653
Exar offers a broad array of power management integrated circuits that are used in a wide variety of end applications.Exar’s state of the art solutions provide high efficiency, low quiescent current, small size and the industry’s best price/performance ratio.Many of Exar’s most advanced power management ICs are offered in thermally enhanced, lead-free DFN or QFN packages for the best blend of low thermal impedance and minimal circuit board area. 

The SP7653 is a synchronous step-down switching regulator optimized for high efficiency. The part is designed to be especially attractive for dual supply, 12 V to 20 V distributed power systems stepped down with 5 V used to power the controller. This lower VCC voltage minimizes power dissipation in the part and is used to drive the top switch.

The SP7653 is designed to provide a fully integrated buck regulator solution using a fixed 1.3 MHz frequency, PWM voltage mode architecture. Protection features include Under Voltage Lock Out (UVLO), thermal shutdown and output short circuit protection.The SP7653 is available in the space saving DFN package.
