AEC-Q101

The Renesas Synchronous Buck Regulator is a high efficiency, dual synchronous step-down DC/DC regulator that can deliver up to 2A/1.7A continuous output current per channel. The channels are 180° out-of phase for input RMS current and EMI reduction. The supply voltage range of 2.8V to 5.5V allows for the use of a single Li+cell, three NiMH cells or a regulated 5V input. The current mode control architecture enables very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL8022 operates at 2.25MHz switching frequency allowing for the use of small, low cost inductors and capacitors.

Dual 2A/1.7A high efficiency synchronous buck regulator with up to 97% efficiency, low iq (40μA)

Selectable forced PWM mode and PFM mode

External synchronization up to 8MHz

Negative current detection and protection

100% maximum duty cycle for lowest dropout

Peak current limiting, hiccup mode short circuit protection and over-temperature protection

Pb-free (RoHs compliant)
