With an integrated 1.4A MOSFET, it can deliver up to 600m A output current at up to 92% efficiency. The adjustable switching frequency is up to 1.2MHz, making it ideal for DSL 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 one Lithium Ion, 3 to 4 Ni MH cells, or 2 cells of alkaline battery. The EL7515 is available in a 10 Ld MSOP package, with maximum height of 1.1mm. With proper external ponents, 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.
