Description

Quad DC/DC µModule Regulator with Configurable 3A Output Array Demonstration circuit 2453A features the LT M ®4643 µModule® regulator , a high performance high efficiency 4 output step-down regulator . The LTM4643EV has an operating input voltage range of 4V to 20V and is able to provide up to 3A out output current from each of its phases. Each output’s voltage is programmable from 0.6V to 3.3V. The LTM4643EV is a complete DC/DC point of load regulator in a thermally enhanced 15mm × 9mm × 1.82mm LGA package requiring only a few input and output ca - pacitors. Output voltage tracking is available through the L, L T , L TC, L TM, Linear Technology, the Linear logo and μModule are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners. BoarD photo TRACK/SS pin for supply rail sequencing. External clock synchronization is also available through the CLKIN pin. The CLKOUT pin provides for synchronization of additional modules’ phases. The LTM4643 data sheet must be read in conjunction with this demo manual for working on or modifying demo circuit 2453A. Design files for this circuit board are available at http://www.linear .com/demo/DC2453A Figure 1. Quad 3A LTM4643; DC2453A

Demonstration circuit 2453A is an easy way to evaluate the performance of the LTM4643EV . Please refer to Figure 1 for test setup connections and follow the procedure below. With power off, place the jumpers in the following positions: JP1 JP2 JP3 JP2 RUN1 RUN2 RUN3 RUN4 ON ON ON ON JP8 JP7 JP6 JP5 MODE1 MODE2 MODE3 MODE4 CCM CCM CCM CCM 2. Before connecting input supply, loads and meters, preset the input voltage supply to be between 4V to 20V. Preset the load currents to 0A. 3. With power off, connect the loads, input voltage supply and meters as shown in Figure 1. Turn on input power supply . The output voltage meters for each phase should display the programmed output voltage ±2%. Once the proper output voltage is established, adjust the load currents for each phase within the 0A to 3A range and observe the load regulation, efficiency, and other parameters. Output voltage ripple should be measured at J6 with a BNC cable and oscilloscope. To obser ve increased light load efficiency place, a Mode pin jumper (JP5-JP8) in the DCM Mode position. performance summary PARAMETER CONDITIONS/NOTES VALUE Input Voltage Range 4V – 20V Output Voltage VOUT Jumper Selectable VOUT1 = 3.3VDC, VOUT2 = 2.5VDC, VOUT3 = 1.5VDC, VOUT4 = 1.2VDC Maximum Continuous Output Current per Phase Derating is Necessary for Certain Operating Conditions.
