Users Manual ISL8117ADEMO3Z Users Manual: Demonstration Board Industrial Analog and Power Rev.0.00 Aug 2017USERS MANUAL ISL8117ADEMO3Z UG134 Rev.0.00 Demonstration Board Aug 3, 2017 1. Overview The ISL8117ADEMO3Z demonstration board (shown in Figure 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 keeps 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. 1.1 Key Features Small, compact design Wide input range: 6V 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, and UVP protection 1.2 Specifications The ISL8117ADEMO3Z demonstration board is designed for high current applications. The current rating of the ISL8117ADEMO3Z is limited by the FETs and inductor selected. The electrical ratings of the ISL8117ADEMO3Z are shown in Table 1. Table 1. Electrical Ratings Parameter Rating Input Voltage 6V to 60V Switching Frequency 300kHz Output Voltage 5V Output Current 6A OCP Set Point Minimum 8A at ambient room temperature 1.3 Ordering Information Part Number Description ISL8117ADEMO3Z High voltage PWM step-down synchronous buck controller 1.4 Related Literature For a full list of related documents, visit our website ISL8117A product page UG134 Rev.0.00 Page 2 of 15 Aug 3, 2017
