Description
The ISL85410DEMO1Z, ISL854102DEMO1Z, andISL85418DEMO1Z boards are intended for use in point-of-loadapplications sourcing from 3V to 40V. The boards are used todemonstrate the performance of the ISL85410, ISL854102,and ISL85418 wide VIN, low quiescent current, high-efficiencysynchronous buck regulators with 1A (ISL85410), 1.2A(ISL854102), and 800mA (ISL85418) output current.The ISL85410, ISL854102, and ISL85418 are offered in a4mmx3mm 12 Ld DFN package with 1mm maximum height.The converter occupies 1.516cm2 area.
Features
- Wide input voltage range 3V to 40V
- Synchronous operation for high efficiency
- No compensation required
- Integrated high-side and low-side NMOS devices
- Selectable PFM or forced PWM mode at light loads
- Internal fixed (500kHz) or adjustable switching frequency300kHz to 2MHz
- Continuous output current up to 1A (ISL85410), 1.2A(ISL854102) and 800mA (ISL85418)
- Internal or external soft-start
- Minimal external components required
- Power-good and enable functions available
