Description

The ISL8117EVAL1Z evaluation board (shown in Figure 1)features the ISL8117. The ISL8117 is a 60V high voltagesynchronous buck controller that offers external soft-start,independent enable functions and integrates UV/OV/OC/OTprotection. Its current mode control architecture and internalcompensation network keep peripheral component countminimal. Programmable switching frequency ranging from100kHz to 2MHz helps to optimize inductor size while thestrong gate driver delivers up to 30A for the buck output.

Characteristics

  • Small, compact design• Wide input range: 4.5V to 60V• High light-load efficiency in pulse skipping DEM operation• Programmable soft-start• Optional DEM/CCM operation• Supports prebias output with SR soft-start• External frequency sync• PGOOD indicator• OCP, OVP, OTP, UVP protection
