Overview The ISL81401EVAL1Z evaluation board (shown in Figure 5 on page 8) features the ISL81401, a 40V high voltage synchronous buck-boost controller that offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimize inductor size while the strong gate driver delivers up to 20A for the buck-boost output. 1.1 Key Features Wide input range: 6V to 40V Bi-directional operation High light-load efficiency in pulse skipping DEM operation Programmable soft-start Optional DEM/PWM operation Optional CC/HICCUP OCP protection Supports prebias output with soft-start PGOOD indicator OVP, OTP, and UVP protection Back biased from output to improve efficiency 1.2 Specifications The ISL81401EVAL1Z evaluation board is designed for high current applications. The current rating of the ISL81401EVAL1Z is limited by the FETs and inductor selected. The ISL81401EVAL1Z electrical ratings are shown in Table 1. Table 1. Electrical Rating Parameter Rating Input Voltage 6V to 40V Switching Frequency 200kHz Output Voltage 12V Output Current 8A OCP Set Point Minimum 10A at ambient room temperature 1.3 Ordering Information Part Number Description ISL81401EVAL1Z High Voltage BUCK-BOOST Controller Evaluation Board 1.4 Related Literature For a full list of related documents, visit our website ISL81401 product page UG188 Rev. 0.00 Page 2 of 21 Oct 25, 2018
