1 / 6 page 09/11/02 IRDCiP1001-B, 200kHz to 300kHz, 20A, 5V IN to 12VIN Single Phase Synchronous Buck Converter using iP1001 Overview In this document, Table 1 and Figure 1 are provided to enable engineers to easily evaluate the iP1001 in a single phase configuration that is capable of providing up to 20A in a lab environment without airflow. Figures 3, 4, 5 and 6 and the complete bill of materials in Table 2 are provided as a reference design to enable engineers to very quickly and easily design a single phase converter. In order to optimize this design to your specific requirements, refer to the iP1001 data sheet for guidelines on external component selection and user adjustable limits and specifications for the iP1001. Custom designs may require layout modifications. Demoboard Quick Start Guide Initial Settings: The output is set to 1.3V, but can be adjusted from 0.925V to 2.0V by setting SW1 according to the VID codes provided in Table 1. The output voltage can be adjusted to allow up to 3.3V OUT by adding R3 & R4 with the DAC set to 2VOUT. Refer to equation 1 for R3 & R4 values. R4 should be removed for output voltages below 2V, and R3 should be set to zero ohms (see Table 2). The switching frequency is centered around 300kHz with the Freq pin floating. The input voltage range can be extended below 5V IN by populating the mini-boost circuit on the demo board. Refer to IRDCiP1001-A reference design documentation for direction on changing the configuration of the demo board. Procedure for Connecting and Powering Up Demoboard: 1. Apply input voltage (5V - 12V) across V IN and PGND. The input voltage (VIN) pin and logic power pin (VDD) are provided as separate inputs. For 5V IN operation only, the VIN and VDD pins can be connected together. For logic power (VDD), connect 5V power source across +5V (TP1) and PGND (TP2). 2. Apply load across VOUT pad and PGND pad. 3. The ENABLE pin is controlled via switch 8 on SW1. This pin is supplied in low state. Once pulled high the output is enabled. 4. Adjust load accordingly. IRDCiP1001-B Recommended Operating Conditions (refer to the iP1001 datasheet for maximum operating conditions) Input voltage: 4.5 - 12V (V DD = 4.5V to 5.5V) Output voltage: DAC selectable between 0.925V - 2.0V (with extended operating range to 3.3V with R3 & R4) Output current: Up to 20A depending on duty factor (refer to load line curve in Fig. 1). Switching Freq: 200kHz or 300kHz selectable.
