ISL98012 NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc 1.8V Input PWM Step-Up Regulator DATASHEET FN6654 Rev 1.00 December 8, 2010 The ISL98012 is a high frequency, high efficiency step-up DC/DC regulator operated in fixed frequency PWM mode. With an integrated 1.4A MOSFET, it can deliver up to 600mA output current at up to 92% efficiency. The adjustable switching frequency is up to 750kHz, making it ideal for common boost applications. When shut down, it draws <1µA of current. This feature, along with the minimum starting voltage of 1.8V, makes it suitable for portable equipment powered by 1 Lithium Ion, 3 to 4 NiMH cells, or 2 cells of alkaline battery.
