Dual 800mA Low Quiescent Current High Efficiency
Synchronous Buck Regulator-Small Form Factor
Description
The ISL8088EVAL2Z kit is intended for use by individuals with
requirements for Point-of-Load applications sourcing from 2.75V
to 5.5V. The ISL8088EVAL2Z board is used to demonstrate the
performance of the ISL8088 low quiescent current mode
converter.
The ISL8088 is offered in a 3mmx3mm 10 Ld DFN package with
1mm maximum height. The complete converter occupies less
than 0.120in 2 area.
Recommended Equipment
The following materials are recommended to perform testing:
? 0V to 10V Power Supply with at least 3A source current
capability or 5V battery
? Electronic Loads capable of sinking current up to 3A
? Digital Multimeters (DMMs)
? 100MHz quad-trace oscilloscope
? Signal generator
Quick Setup Guide
1. Ensure that the circuit is correctly connected to the supply and
loads prior to applying any power.
2. Connect the bias supply to VIN. Plus terminal to VIN and
negative return to P1.
3. Turn on the power supply.
4. Verify the output voltage is 2.5V for V OUT1 and 1.8V for V OUT2.
