ISL78228ARZ - Renesas Electronics

Description: The ISL78228 is a high efficiency, dual synchronous step-down DC/DC regulator that can deliver up to 800mA continuous output current per channel. The supply voltage range of 2. 75V to 5. 5V allows for the use of a 3. 3V or 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 ISL78228 operates above the AM radio band as well as the 2. 25MHz switching frequency, allowing for the use of small, low
