Overview
Description
The ISL8088EVAL1Z evaluation board is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.75V to 5.5V. This evaluation board is used to demonstrate the performance of the ISL8088 low quiescent current mode converter.
Features
- Dual 800mA high-efficiency synchronous buck regulator with up to 97% efficiency
- 800mA guaranteed output current per channel
- Power-good (PG) output with 1ms delay
- 2.75V to 5.5V supply voltage
- 3% output accuracy over temperature/load/line
- Start-up with pre-biased output
- Internal digital soft-start - 2ms
- Soft-stop output discharge during disabled
- 30µA quiescent supply current in PFM mode
- Selectable forced PWM mode and PFM mode
- External synchronization up to 4MHz
- Typical 6.5µA logic controlled shutdown current
- 100% maximum duty cycle for lowest dropout
- Internal current mode compensation
- Peak current limiting
- Over-temperature protection
- Independent enable
