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. Custom designs may require
layout modifications.
Demoboard Quick Start Guide
Initial Settings:
z
The output is set to 2V, 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 also be adjusted to allow up to
2.5V
for 3.3V
, by adding R3 & R4 with the DAC set to 2V
. 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).
z
The switching frequency is centered around 200kHz for <5V
applications with the FREQ pin connected to V
.
z
The input voltage range can be increased to allow operation between 5V
IN
and 12V
IN
. Refer to IRDCiP1001-B reference
design documentation for direction on changing the configuration of the demo board.
Procedure for Connecting and Powering Up Demoboard:
1. Apply input voltage (3.3V-4.5V) across V
IN
and PGND. Note that this demo board has a mini-boost circuit
provided in order to provide the 5V
DD
internal logic for the iP1001. This boost circuit can be used to provide power for
up to 5 x iP1001 devices simultaneously.
2. Apply load across VOUT pad and PGND pad.
3. Make sure Jumpers JP2 and JP3 are connected.
4. Remove jumper JP1 to turn on the boost circuit and pull iP1001 ENABLE pin high. The ENABLE pin is controlled via switch
8 on SW1. This pin is supplied in low state, once pulled high the output is enabled.
5. Adjust load accordingly.
