概要
説明
The ISL8022EVAL1Z evaluation kit is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.8V to 5.5V. This evaluation board is used to demonstrate the performance of the ISL8022 low quiescent current mode converter.
特長
- Dual 2A/1.7A high-efficiency synchronous buck regulator with up to 97% efficiency
- 180° out-of-phase
- Power-good (PG) output with 1ms delay
- 2.8V to 5.5V supply voltage
- 3% output accuracy over temperature/load/line
- Start-up with pre-biased output
- 40µA quiescent supply current in PFM mode
- Selectable forced PWM mode and PFM mode
- External synchronization up to 8MHz
- Typical 6.5µA logic controlled shutdown current
- 100% maximum duty cycle for lowest dropout
- Internal current mode compensation
- Peak current limiting, hiccup mode short circuit protection and over-temperature protection
- Negative current detection and protection
- Internal digital soft-start - 5ms
- Soft-stop output discharge during disabled
アプリケーション
- DC/DC POL modules
- µC/µP, FPGA and DSP power
- Plug-in DC/DC modules for routers and switchers
- Test and measurement systems
- Li-ion battery powered devices
- Barcode readers
