DESCRIPTION
FEATURES
The output current can be up to 8A. An internal n Output current up to 8A regulator converts bus voltage to 5V, which provides volt- n Prebias Startup age supply to internal logic and driver circuit. The NX9521 n Less than 50 nS adaptive deadband has programmable frequency feature and operates at n Programmable loss-less Over Current Protection 300kHz when Rt pin is open, employs programmable n No negative spike at Vout during startup and shut- loss-less current limiting by sensing the Rdson of syn- down chronous MOSFET followed by hiccup feature. Feed- n Over Voltage Protection triggers latch out back under voltage triggers hiccup. n Power Good indicator available Other features of the device are: Over voltage protection, n Pb-free and RoHS compliant thermal shutdown, 5V gate drive, Adaptive deadband control, Internal digital soft start, Vcc undervoltage lock out APPLICATIONS
and shutdown capability via the comp pin. NX9511 is n Graphic Card on board converters av...
