Beschreibung

The ISL81802EVAL1Z dual-phase evaluation board (shown in Figure 4) features the ISL81802, an 80V high voltage dual synchronous buck controller that offers external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 1MHz helps to optimize inductor size while the strong gate driver delivers up to 20A for the buck output.

Eigenschaften

  • Wide input range: 18V to 80V
  • High light-load efficiency in pulse skipping DEM operation
  • Programmable soft-start
  • Optional DEM/PWM operation
  • Optional CC/HICCUP OCP protection
  • Supports pre-bias output with soft-start
  • PGOOD indicator
  • OVP, OTP, and UVP protection
  • Back biased from output to improve efficiency
