EC9483 EC9483 3A 380KHZ 28V PWM Buck DC/DC Converter
General Description
The EC9483 is a 380 KHz fixed frequency monolithic step down switch mode
regulator with a built in internal Power MOSFET.
It achieves 3A 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 c ircu i t protection function are built inside.
An internal compensation block is built in to minimize external component count.
