Overview

® ISL6610, ISL6610A Data Sheet November 22, 2006 FN6395.0 Dual Synchronous Rectified MOSFET Drivers The ISL6610, ISL6610A integrates two ISL6609, ISL6609A drivers with enable function removed and is optimized to drive two independent power channels in a synchronousrectified buck converter topology.

These drivers, combined with an Intersil ISL63xx or ISL65xx multiphase PWM controller, form a complete high efficiency voltage regulator at high switching frequency.

The IC is biased by a single low voltage supply (5V), minimizing driver switching losses in high MOSFET gate capacitance and high switching frequency applications.

Key Features

  • 4A typical sink current for the lower gate driver, enhancing the lower MOSFET gate hold-down capability during PHASE node rising edge, preventing power loss caused by the self turn-on of the lower MOSFET due to the high dV/dt of the switching node. The ISL6610, ISL6610A also features an input that recognizes a high-impedance state, working together with Intersil multiphase PWM controllers to prevent negative transients on the controlled output voltage when operation is suspended. This feature el.
