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-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. 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 mode operation provides high efficiency by reducing switching losses at light loads. In PFM mode of operation, both channels draw a total quiescent current of only 40µA, hence enabling high light load efficiency in order to maximize battery life. The ISL8022 offers a 1ms Power-Good (PG) to monitor both outputs at power-up. When shutdown, ISL8022 discharges the outputs capacitor. Other features include internal digital soft-start, enable for power sequence, overcurrent protection, and thermal shutdown.
