Product Overview

The MAX8646ETG+ is a 6A, 2MHz step-down regulator with integrated switch in 24 pin TQFN package. The high efficiency switching regulator delivers up to 6A load current at output voltages from 0.6V to 0.9 x VIN. The IC operates from 2.35V to 3.6V making it ideal for onboard point-of-load and post regulation applications. Total output error is less than ±1% over load, line and temperature ranges. It operates in fixed-frequency PWM mode with a switching frequency range of 500KHz to 2MHz set by an external resistor. High-frequency operation allows for an all-ceramic capacitor design. The high operating frequency also allows for small-size external components. The low-resistance on-chip nMOS switches ensure high efficiency at heavy loads while minimizing critical inductances. IC comes with a high bandwidth (> 14MHz) voltage-error amplifier. It is used in ASIC/CPU/DSP core & I/O voltages, POLs, DDR, base-station, RAID control, telecom & networking power supplies.
  • Operating temperature range from 40°C to +85°C
  • Internal 23Mohm RDS(ON) MOSFETs
  • Continuous 6A output current
  • Adjustable output from 0.6V to (0.9 x VIN)
  • Soft start reduces inrush supply current
  • Compatible with ceramic, polymer and electrolytic output capacitors
  • VID selectable output voltages 0.6V, 0.7V, 0.8V, 1V, 1.2V, 1.5V, 1.8V, 2V and 2.5V
  • Fully protected against overcurrent and overtemperature
  • Safe start into pre-biased output
  • Sink/source current in DDR applications
