Monolithic Power Systems MP9928 | Demoboard EV9928-L-00C

Description

The EV9928-L-00C Evaluation Board isdesigned to demonstrate the capabilities ofMP9928. The MP9928 is a high-voltage,synchronous step-down controller that directlysteps down voltages from up to 60V. The MP9928 uses PWM current control architecturewith accurate cycle-by-cycle current limiting andis capable of driving dual N-channel MOSFETs.The operating frequency of the MP9928 can beprogrammed by an external resistor orsynchronized to an external clock for noisesensitive applications. Full protection featuresinclude precision output over-voltage protection(OVP), output over-current protection (OCP),and thermal shutdown.The MP9928 is available in TSSOP20-EP andQFN-20 (3mmx4mm) packages. This board isavailable in QFN-20 (3mmx4mm) package.
