MAX77540

16Vin/6A, Dual-Phase High-Efficiency Buck Converter

MAX77540 is a high efficiency step-down converter with two 3A switching phases. It uses an adaptive COT (constant on-time) current-mode control architecture and the two 3A switching phases can be configured as either one (2Φ, 6A) or two (1Φ, 3A each) outputs. Its wide input voltage range enables a direct conversion for sub-1V outputs from 3-cell Li+ batteries, USB PD, and 12VDC supply rails. The output voltages are preset with resistors and are further adjustable through an I2C-compatible interface. With 94% peak efficiency, low quiescent current, and compact solution size, the MAX77540 is ideal for battery-powered, space-constraint equipment.

Key Features and Benefits

  • 4V to 16V input voltage for single stage conversion
  • 94% peak efficiency (7.6VIN, 3.3VOUT) extends battery life
  • Less than 55mm2 total solution size for high power density
