EL7512 General Description
The EL7512 is a high frequency, high efficiency step-up DC:DC regulator operated at fixed frequency PWM mode.With an integrated 1A MOSFET, it can deliver up to 600mA output current at up to 90% efficiency. The adjustable switching frequency is up to 1.2MHz, making it ideal for DSL applications.
When shut down, it draws <3µA of current. This feature,along with the minimum starting voltage of 2V, makes it suitable for portable equipment powered by one lithium ion or 3 to 4 NiMH cells.
The EL7512 is available in a 10-pin MSOP package, with 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.
