概要
説明
The ISL8026AEVAL3Z evaluation board is intended for use by customers with requirements for point-of-load (POL) applications sourcing from 2.5V to 5.5V. The board is used to demonstrate the performance of the ISL8026A, low quiescent, high-efficiency synchronous buck regulators.
The ISL8026A is offered in a 3mm x 3mm 16 Ld TQFN package with a 1mm maximum height. The complete area that the converter occupies can be as small as 141.935mm2.

- High-efficiency synchronous buck regulator with up to 95% efficiency
- 1% reference accuracy over load/line/temperature (-40 °C to +85 °C)
- Start-up with prebiased output
- Internal soft-start - 1ms or adjustable
- Soft-stop output discharge during disabled
- Adjustable frequency from 500kHz to 4MHz - Default at 1MHz (2MHz for ISL8026A)
- External synchronization up to 4MHz
- Negative OC protection
