Product Overview

ISL6617AFRZ-TK is a PWM doubler with output monitoring feature. It uses Intersil’s proprietary phase doubler scheme to modulate two-phase power trains with single PWM input. It doubles the number of phases that 3.3V multiphase controllers can support. It is designed to minimize the number of analogue signals that interface between the controller and drivers in high phase count scalable applications. The common COMP signal, which is usually seen in conventional cascaded configurations, is not required; this improves noise immunity and simplifies the layout. Furthermore, it provides low part count and low cost advantage over the conventional cascaded technique. Application includes high current, low voltage DC/DC converters, high frequency and high efficiency VRM and VRD, high phase count and phase shedding applications, 3.3V PWM input integrated power stage or DrMOS.
  • Proprietary phase doubler scheme, enhanced light- to full-load efficiency
  • Double or quadruple phase count
  • Patented current balancing with DCR current sensing and adjustable gain
  • Current monitoring output (IOUT) to simplify system interface and layout
  • Triple-level enable input for mode selection
  • Dual PWM output drives for two synchronous rectified bridges with single PWM input
  • Support 3.3V PWM input, support 5V PWM output, overvoltage protection
  • Compatible with DCR sensing or smart power stage sensing
  • Tri-state PWM input and outputs for output stage shutdown
  • 10 lead DFN package, operating temperature range from -40 to +125°C
