Output Synchronous Buck Converter using iP1202

Overview

The iP1202 is fully optimized solution for medium current synchro-

nous buck applications requiring up to 15A or 30A. In this document,

Fig. 1 and 2 are provided to enable engineers to easily evaluate the

iP1202 in an independent and parallel configuration that is capable of

providing up to 15A per phase with double-sided heat sinking. Fig. 4, 5

and 6 and the complete bill of materials in Table 1 are provided as a

reference design to enable engineers to very quickly and easily design

a dual phase converter. In order to optimize this design to your

specific requirements, refer to the iP1202 data sheet for guidelines on

external component selection and user adjustable limits and specifi-

cations. Custom designs may require layout modifications.

Demoboard Quick Start Guide

Initial Settings:

•

The output1 is set to 1.5V and output2 is set to 2.5V for independent configuration.

The output1 is set to 1.5V with R4, R8, R10, R11 and R12 removed for parallel configuration.

Output can be adjusted from 0.8V to 3.3V as follow:

1. V

: R9=R13= R7 [(V_{OUT 1}/ Vref) – 1]. Set R7=R14=1k,Vref=0.8V

2. V_OUT2

^OUT1: R10=R11= R8 [(V_OUT2/ Vref) – 1]. Set R8=R12=1k,Vref=0.8V.

•

The switching frequency is set to R3=30.9k for 300kHZ

The input voltage range can be increased to allow operation between 5.5V_INand 13.2V_IN.

For paralleled single output operation see Fig. 6 for configuration table in reference design

schematic.

Procedure for Connecting and Powering Up Demoboard:

Apply input voltage (5.5V-13.2V) across V_INand PGND

Apply load across VOUT1 pad and PGND pad and VOUT2 pad and PGND pad for independent

configuration.

Apply load across VOUT1 pad and PGND pad and short R27 for parallel configuration.

Adjust load accordingly.

IRDCiP1202-A Recommended Operating Conditions

(refer to the iP1202 datasheet for maximum operating conditions)

Input voltage:

5.5 - 13.2V

Output voltage: Can be set between 0.8V – 3.3V

Output current: Up to 15A (see recommended operating area Fig. 1, 2 and 3). The maximum current

should be limited to 11.5A if the PCB is the only heat sink.

Switching Freq: 200kHz to 400kHz selectable.
