Not Recommended For New Designs

The SC1218 is a high speed, robust, dual output driver to drive high-side and low-side N-MOSFETs in synchronous buck converters. Combined with Semtech’s multi-phase PWM controller SC2649, one can build high performance, versatile voltage regulators for next generation microprocessors.

Features


  • Advanced digital timing to filter out very narrow PWM pulses
  • +12 V gate drive voltage
  • Integrated Bootstrap Diode
  • High peak drive current
  • Adaptive non-overlapping gate drives provide shoot-through protection
  • Support Dynamic VID operation
  • Ultra-low propagation delay
  • Floating top gate drive
  • Crowbar function for over-voltage protection
  • High-frequency (to 2 MHz) operation allows use of small inductors and low-cost ceramic capacitors
  • Under-voltage lockout
  • Low quiescent current
  • Enable function for both gate OFF shut-down
  • MLPQ-8 and SOIC-8 packages

Applications


  • Intel® next generation processor power supplies
  • AMD® Athlon™ and K8™ processor power supplies
  • High-current low-voltage DC-DC converters

Packaging

SOIC-8 EDP / MLP8
