Low-Cost, Dual-Output, Step-Down Controller with Fast Transient Response
General Description
The MAX8664 dual-output PWM controller is a low-cost, high-performance solution for systems requiring dual power supplies.
It provides two individual outputs that operate 180° out-of-phase to minimize input current ripple, and therefore, capacitance requirements.
Built-in drivers are capable of driving external
MOSFETs to deliver up to 25A output current from each channel.
The MAX8664 operates from a 4.
5V to 28V input
voltage source and generates output
voltages from 0.
6V up to 90% of the input
voltage on each channel.
Total output regulation error is less th...
