10A 5V/12V Step-Down Converter
EM5810/A
General Description
EM5810/A is a synchronous rectified PWM
controller with a built in high-side power MOSFET
operating with 5V or 12V supply voltage. It
achieves 10A peak output current with excellent
load and line regulation. This device operates at
200/300kHz and provides an optimal level of
integration to reduce size and cost of the power
supply.
This part includes internal soft start, internal
compensation networks, over current protection,
under voltage protection, and shutdown function.
This part is available in SOP-8/PSOP-8 package.
