The EL7515 is a high frequency, high efficiency step-up DC/DC
regulator operated at fixed frequency PWM mode.
With an integrated 1.
4A MOSFET, it can deliver up to 600mA 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 NiMH cel...
