MAX8654ETX+

The MAX8654ETX+ is a 12V, 8A, 1.2MHz step down regulator in 36 pin TQFN package. The MAX8654 high-efficiency switching regulator delivers up to 8A of load current at output voltages from 0.6V to 0.85 x VIN. Ideal for on-board point of load and post regulation 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. 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.

• Supply voltage range is 4.5V to 14V
• Operating temperature range from -40°C to 85°C
• Internal 26mohm RDS(ON) MOSFETs
• Adjustable overcurrent protection
• Soft-start reduces inrush supply current
• High bandwidth (20MHz) voltage error amplifier
