ISL8025IRTAJZ-T7A - Brand New RENESAS DC Switching Regulators
-
**The ISL8025, ISL8025A are highly efficient, monolithic, synchronous
step-down DC/DC converters that can deliver 5A of continuous output current from a 2.7V to 5.5V input supply. The devices use current mode control architecture to deliver a very low duty cycle operation at high frequency with fast transient response and excellent loop stability.**
The ISL8025, ISL8025A integrates a very low ON-resistance P-Channel (45mΩ) high-side FET and N-Channel (19mΩ) low-side FET to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 225mV dropout voltage at 5A output current. The operation frequency of the pulse-width modulator (PWM) is adjustable from 500kHz to 4MHz. The default switching frequency, which is set by connecting the FS pin high, is 1MHz for the ISL8025 and 2MHz for the ISL8025A.
The ISL8025, ISL8025A can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference, while discontinuous mode provides higher efficiency by reducing switching losses at light loads.Features
