Product Overview

The MAX797ESE+ is a step-down controller with synchronous rectifier for CPU power in 16 pin NSOIC package. The high performance, step-down DC-DC converter with single or dual outputs provides main CPU power in battery-powered systems. This buck controller achieve 96% efficiency by using synchronous rectification and Idle Mode control scheme to extend battery life at full-load (up to 10A) and no-load outputs. Excellent dynamic response corrects output transients caused by latest dynamic-clock CPUs within five 300KHz clock cycles. Unique bootstrap circuitry drives inexpensive N-channel MOSFETs, reducing system cost and eliminating crowbar switching currents found in some PMOS/NMOS switch designs. It has a logic-controlled and synchronized fixed frequency pulse width modulating (PWM) operating mode which reduces noise and RF interference in sensitive mobile communications and pen entry applications.
  • Supply voltage range is 5V to 30V
  • Operating temperature range from -40°C to 85°C
  • Adjustable output range from 2.5V to 6V
  • Preset 3.3V and 5V outputs (at up to 10A), automatic bootstrap circuit
  • Multiple regulated outputs, +5V linear regulator output
  • Maximum precision reference output is 2.55V (no external load), typical shutdown current is 1µA
  • 150KHz/300KHz fixed frequency PWM operation
  • Maximum dropout power consumption is 8mW
  • Maximum quiescent power consumption is 6.6mW
  • Programmable soft start
