Users Manual ISL8215MEVAL2Z Users Manual: Evaluation Board Industrial Analog and Power Rev.1.00 Jan 2019USERS MANUAL ISL8215MEVAL2Z UG145 Rev.1.00 Evaluation Board Jan 23, 2019 1. Overview The ISL8215MEVAL2Z evaluation board (shown in Figure 1) features the ISL8215M. The ISL8215M is a single channel synchronous step-down power supply, capable of delivering up to 15A of continuous current and optimized for high power density applications without the need for airflow or heatsink. The ISL8215MEVAL2Z evaluation board is a 1.8inx3in 4-layer FR4 board with 2oz. copper on all layers. Operating from a single 7V to 42V wide input power rail, the ISL8215MEVAL2Z evaluation board offers adjustable output voltages down to 0.6V and efficiencies up to 96.5%. It is based on a valley current mode PWM control scheme with V feed forward, which provides a fast transient response and excellent loop stability. The ISL8215MEVAL2Z IN evaluation board programs switching frequencies up to 2MHz, with the additional option of synchronizing to an external clock through the SYNC pin. A selectable Pulse Skipping Mode (PSM) with Diode Emulation Mode (DEM) can be enabled to improve light-load efficiency for battery-related applications. The evaluation board also features output voltage tracking that can be implemented through the SS/TRK pin. By default, the board is set to a 3.3V output voltage with a 300kHz switching frequency. 1.1 Key Features Wide input voltage range from 7V to 42V Adjustable output voltage from 0.6V to 12V with 1.5% accuracy over line, load, and temperature Up to 96.5% conversion efficiency High light-load efficiency with pulse skipping DEM operation Programmable soft-start with output voltage tracking Prebias output start-up External frequency synchronization up to 1MHz Dedicated enable pin and PGOOD indicator UVLO, programmable overcurrent, overvoltage, and over-temperature Thermally enhanced 19mmx13mmx5.3mm HDA package 1.2 Specifications The evaluation board has been configured and optimized for the following operating conditions: V = 7V to 42V IN V = 3.3V OUT I = 15A OUT-MAX f = 300kHz SW 1.3 Ordering Information Part Number Description ISL8215MEVAL2Z ISL8215M single 15A power module evaluation board UG145 Rev.1.00 Page 2 of 14 Jan 23, 2019
