产品概述

The MAX756CPA+ is a CMOS Step-up DC-DC Switching Regulator for small, low input voltage or battery-powered systems. The MAX756 accepts a positive input voltage down to 0.7V and converts it to a higher pin-selectable output voltage of 3.3V or 5V. Typical full-load efficiencies for the MAX756 is greater than 87%. The MAX756 provide three improvements over previous devices. Physical size is reduced-the high switching frequencies (up to 0.5MHz) made possible by MOSFET power transistors allow for tiny (<5mm diameter) surface-mount magnetic. Efficiency is improved to 87% (10% better than with low-voltage regulators fabricated in bipolar technology). Supply current is reduced to 60µA by CMOS construction and a unique constant-off-time pulse-frequency modulation control scheme.
  • Operates down to 0.7V input supply voltage
  • 87% Efficiency at 200mA
  • 60µA Quiescent current
  • 20µA Shutdown mode with active reference and LBI detector
  • ±1.5% Reference tolerance over-temperature
  • Low-battery detector (LBI/LBO)
  • 500kHz Maximum Switching Frequency
  • Operates Down to 0.7V Input Supply Voltage
