Overview: DATASHEET ISL6430
Single Sync Buck PWM Controller for Broadband Gateway Applications FN9017 Rev 2.00 Jul 15, 2003 The ISL6430 provides plete control and protection for a DC-DC converter optimized for high-performance broadband gateway applications. It is designed to drive two N Channel MOSFETs in a synchronous-rectified buck topology. The ISL6430 integrates all of the control, output adjustment, monitoring and protection functions into a single package.
The output voltage of the converter can be precisely regulated to as low as 1.27V, with a maximum tolerance of 1% over temperature and line voltage variations.
The ISL6430 provides simple, single feedback loop, voltagemode control with fast transient response. It includes a 200kHz free-running triangle-wave oscillator that is adjustable from below 50kHz to over 1MHz.
