Overview
DATASHEET ISL8022 Dual 2A/1.
7A Low Quiescent Current 2.
25MHz High Efficiency Synchronous Buck Regulator FN7650 Rev 3.
00 March 14, 2013 The ISL8022 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-ofphase 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.
Each channel is optimized for generating an output voltage as low as 0.
6V.
The ISL8022 has a user configurable mode of operation-forced PWM mode and PFM/PWM mode.
The forced PWM mode operation reduces noise and RF interference while the PFM mod...
