ISL8033EVAL1Z Dual 3A Low Quiescent Current

High Efficiency Synchronous Buck Regulator

Description

The ISL8033EVAL1Z kit is intended for use by

individuals with requirements for Point-of-Load

applications sourcing from 2.85V to 6V. The

ISL8033EVAL1Z evaluation board is used to demonstrate

the performance of the ISL8033 low quiescent current

mode converter.

The ISL8033 is offered in a 4mmx4mm 24 Ld QFN

package with 1mm maximum height. The complete

converter occupies less than 5.46cm

Key Features

• Dual 3A High Efficiency Synchronous Buck Regulator

• 180° Out-of-Phase

• Power-Goods (PG) Output with 1ms Delay

• 2.85V to 6V Supply Voltage

• 2% Output Accuracy Over-temperature/Load/Line

• Start-up with Pre-biased Output

• Internal Digital Soft-Start - 1.5ms

• Soft-Stop Output Discharge During Disabled

• External Synchronization up to 6MHz

• Typical 8µA Logic Controlled Shutdown Current

• 100% Maximum Duty Cycle for Lowest Dropout

• Internal Current Mode Compensation

• Peak Current Limiting, Hiccup Mode Short Circuit

• Negative Current Detection and Protection

Recommended Equipment

The following materials are recommended to perform

testing:

• 0V to 10V Power Supply with at least 3A source

• Electronic Loads capable of sinking current up to 3A

• Digital Multimeters (DMMs)

• 100MHz quad-trace oscilloscope

• Signal generator

with up to 95% Efficiency

Quick Setup Guide

Evaluating the Other Output Voltage

The ISL8033EVAL1Z kit output is preset to 1.8V for

can be adjusted from 0.8V to 3.3V. The output voltage

programming resistor, R2 (or R5 in Channel 2), will

depend on the desired output voltage of the regulator.

The value for the feedback resistor is typically between

0Ω and 750kΩ as shown in Equation 1.

Let’s set R3/R6 = 100kΩ, then R2/R5 will be:

If the output voltage desired is 0.8V, then R3 is left

unpopulated and short R2. For faster response

performance, add 47pF in parallel to R2.

Mode Control

The ISL8033 has a SYNC pin. Connects to logic high or

input voltage VIN for PWM internal synchronization.

Connect to an external function generator for external

Synchronization. Negative edge trigger. Do not leave this

pin floating. Do not tie this pin low (or to GND).
