EL7515
FN7120.2
High Frequency PWM Step-Up Regulator
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 cells, or 2 cells of alkaline battery.
The EL7515 is available in a 10 Ld 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.
