Description
The MAX8654 is a high-efficiency switching regulator that delivers up to 8A of load current at output voltages from 0.6V to 0.85 x VIN. It operates from 4.5V to 14V, making it ideal for on-board point-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 soft-start to accommodate different types of output capacitors and reduce input inrush current. The MAX8654 is available in a 36-lead TQFN package.
