Description

ISL8117A-LDEMO2Z Buck-Boost Board User-guideThe ISL8117A-LDEMO2Z (shown in Figure 4 on page 4) features the ISL8117A. The ISL8117A is a 60V high-voltage, synchronous buck controller that offers external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. Its current mode control architecture and internal compensation network keep peripheral component count minimal. Programmable switching frequency ranging from 100kHz to 2MHz helps to optimize inductor size, while the strong gate driver delivers up to 30A for the buck output.

Characteristics

  • Small, compact design• Wide input range: 6.5V to 42V• Programmable soft-start• Supports prebias output with SR soft-start• External frequency sync• PGOOD indicator• OCP, OVP, OTP, UVP protection
