High Frequency Pwm Step-up RegulatorThe 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 <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 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 -40C to
+85C temperature range. By Intersil Corporation
