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.
The ISL98012 is available in a 10 Ld MSOP package, with a maximum height of 1.1mm. With proper external components, the whole converter takes less than 0.25in2 PCB space.
This device is specified for operation over the full -40°C to +85°C temperature range.
