Meritorious performance from N-channel MOSFETs
Continuing the expansion of its portfolio of low-voltage power MOSFETs for switching and power management applications, ON Semiconductor has released a range of new N-channel devices.
Ideal applications for the device include the drive voltage for ORing diodes, floating supervisory circuits and LED drivers.
Whereas most charge pumps typically have their output voltage referenced to ground, the NIS6201 output voltage can be referenced (or added to) any bus voltage.
This allows it to 'float' a bias or supply voltage on top of any bus voltage.
This device enables designers to easily generate any bias voltage with minimal external components.
The NIS6201 contains an internal linear regulator and a versatile charge pump that allow bias voltage supplies to be transferred from a ground referenced source to a higher potential.
Because the high voltage components are external to the pump and can be sized accordingly, the NIS6201 can handle any isolation voltage required - up to hundreds of volts.
The device also features an adjustable voltage output and is thermally protected.
Using the NIS6201, designers can easily create a bias voltage with few external components and no inductor, thus reducing size, weight and cost.
"The NIS6201 is a big step forward in designing economical 'housekeeping' supplies - or the auxiliary supplies needed to provide power to the main PWM control IC or to power ICs for functions that aren't always on", said Sue Nee, Marketing Manager of Application Specific Integrated Products at ON Semiconductor.
"If an additional output voltage is required late in a design cycle, the NIS6201 can be a quick and easy solution".
The NIS6201 is offered in a lead-free, SO-8 package.
Samples and a demo-board are available.
