Description
The MP2918 is a high-voltage, synchronous, step-down, switching controller that can directly step down voltages from up to 40V. The MP2918 uses PWM current control architecture with accurate cycle-by-cycle current limit and is capable of driving dual N-channel MOSFET switches.
Advanced Asynchronous Mode (AAM) enables non-synchronous operation to optimize light-load efficiency.
The operating frequency of the MP2918 can be programmed by an external resistor or synchronized to an external clock for noise-sensitive applications. Full protection features include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown.
The MP2918 is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages.
