GreenFET3 SLG59M1730C Layout Guide Content 1. Description 2. Power and Ground Planes 3. Basic Test Setup and Connections Description The SLG59M1730C is a 29 m, ~ 1 A single- channel load switch that is able to switch 2.5 V to 5.5 V power rails. The product is packaged in an ultra-small 0.8 x 0.8 mm package.

The trace length from the control IC to the ON pin about the PCB layout of SLG59M1730C applications. (PIN1) should be as short as possible and must SILEGO WLCSP 0.8x0.8-4L PKG Unit: um avoid crossing this trace with power rails. 2.2. The D/VIN and S/VOUT pins carry significant current. Please note how the D/VIN and S/VOUT pads are placed directly on the power planes in Figure 3, which minimizes the RDS associated ON with long, narrow traces. The D/VIN, S/VOUT and GND pins dissipate most of the heat generated during high-load current condition. The layout shown in Figure 3 is illustrating a proper solution for heat to transfer as efficiently as possible out of the device. 2.3. The GND pin (A2) should be connected to GND. 2.4. 2 oz. copper is recommended for higher currents. Figure 2. SLG59M1730C Package Dimensions and Recommended Land Pattern
