MP9928GF-Z

The MP9928 is a high-voltage, synchronous step-down switching regulator controller that can directly step down voltages from up to 60V. The MP9928 uses PWM current control architecture with accurate cycle-by-cycle current limiting. It is capable of driving dual N-channel MOSFET switches.AAM Mode (Advanced asynchronous mode) enables non-synchronous operation and PFM mode to optimize light load efficiency.The operating frequency of MP9928 can be programmed by an external resistor or synchronized to an external clock for noise-sensitive applications. Fault protections are available including a precision output over voltage protection (OVP), output over current protection (OCP), and thermal shutdown.The MP9928 is available in TSSOP20-EP package and QFN-20 (3mmx4mm) package. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
