MAX8654 12V, 8A, 1.2MHz, Step-Down Regulator

The MAX8654 high-efficiency Switching Regulator delivers up to 8A of load current at output voltages from 0.6V to 0.85 x VIN. The IC operates from 4.5V to 14V, making it ideal for on-board poi 4fe nt-of-load and postregulation applications, with total output error less than 1% over load, line, and temperature ranges. The MAX8654 is a fixed-frequency PWM mode Regulator with a switching frequency range of 250kHz to 1.2MHz set by an external resistor or SYNC input. High-frequency operation allows for an all-ceramic-capacitor solution. A SYNCOUT output is provided to synchronize a second Regulator switching 180 out-of-phase with the first to reduce the input ripple current and consequently reduce the required input capacitance. The high operating frequency minimizes the size of external components. The on-board low RDS(ON) dual-nMOS design keeps the board cooler at heavy loads while minimizing the critical inductances, making the layout a much simpler task with respect to the Discrete solutions. The MAX8654 comes with a high-bandwidth (20MHz) voltage-error Amplifier The voltage-mode control architecture and the op-amp voltage-error Amplifier permit a type 3 compensation scheme to be utilized to achieve maximum loop bandwidth, up to 20% of the switching frequency. High loop bandwidth achieves fast transient response resulting in less output capacitance required. The MAX8654 offers programmable sof 50e t-start to accommodate different types of output capacitors and reduce input inrush current. The MAX8654 is available in a 36-pin lead-free thin QFN package.
