ME5513 Datasheet Text
2A 380KHZ 25V PWM Buck DC/DC Converter
General Description
The ME5513 is a 380 KHz fixed frequency monolithic step down switch mode regulator with a built in internal Power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation.
The device includes a voltage reference, oscillation circuit, error amplifier, internal PMOS and etc.
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function and a short circuit protection function are built inside. An internal pensation block is built in to minimize external ponent count.
The ME5513 serves as ideal power supply units for portable devices.
