FN7120 High Frequency PWM Step-Up Regulator Rev 2.00 August 10, 2007 The EL7515 is a high frequency, high efficiency step-up
Features
DC/DC regulator operated at fixed frequency PWM mode. With an integrated 1.4A MOSFET, it can deliver up to 600mA • Up to 92% efficiency output current at up to 92% efficiency. The adjustable • Up to 600mA IOUT switching frequency is up to 1.2MHz, making it ideal for DSL • 4.5V < V applications. OUT < 17V • 1.8V < V When shut down, it draws <1µA of current. This feature, IN < 13.2V along with the minimum starting voltage of 1.8V, makes it • Up to 1.2MHz adjustable frequency suitable for portable equipment powered by one Lithium Ion, • <1µA shutdown current 3 to 4 NiMH cells, or 2 cells of alkaline battery. • Adjustable soft-start The EL7515 is available in a 10 Ld MSOP package, with • Low battery detection maximum height of 1.1mm. With proper external components, the whole converter takes less than 0.25in2 • Internal thermal protection PCB space. • 1.1mm max height 10 Ld MSOP package This device is specified for operation over the full -40°C to • Pb-Free available (RoHS compliant) +85°C temperature range.
