General Description
The EL7512C 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, mak-
ing it ideal for DSL applications.
When shut down, it draws <3A 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 EL7512C is available in a 10-pin MSOP package, with maximum
height of 1.1mm. With proper external components, the whole con-
verter takes less than 0.25in2 PCB space.
This device is specified for operation over the full -40°C to +85°C
temperature range.
