High Frequency Pwm Step-up Regulator

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 <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
