Product Overview

The MAX8815AETB+T is a 1A, 97% efficiency, 30µA quiescent current step-up converter with True Shutdown in 10 pin TDFN package. This DC to DC step-up converter is a high-efficiency, low quiescent current, synchronous step-up converter with True Shutdown and inrush-current limiting. It generates any output voltage from 3.3V to 5V from a 2-cell NiMH/NiCd or a single-cell Li+/Li polymer battery. The MAX8815A uses two modes of operation. The first mode of operation uses only 30µA quiescent current and allows the converter to switch only when needed at no load and light loads. Under moderate and heavy loads (typically above 90mA), the MAX8815A uses a fixed-frequency pulse-width modulation (PWM) technique. This mode allows maximum efficiency at light loads. The second mode of operation is a fixed-frequency forced-pulse-width modulation (FPWM) mode where the converter switches at a fixed frequency irrespective of the load. This mode allows for easy noise filtering and lower output ripple.
  • Supply voltage range is 1.2V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Preset 2.5A current limit
  • 500mA load at 1.8V input and output is set to 5V
  • 1A load at 2.5V input and output is set to 5V
  • Controlled current in soft start limits inrush current
  • Internal compensation
  • Overload/short circuit protection and thermal shutdown
  • Shutdown current is 0.1µA
