产品概述

The MAX685EEE+ is a dual-output (positive and negative), DC-DC converter for CCD and LCD in 16 pin QSOP package. This device uses a single inductor to provide independently regulated positive and negative outputs. It alternates between acting as a step-up converter and as an inverting converter on a cycle-by-cycle basis. Both output voltages are independently regulated. Output ripple magnitude is 30mVp-p. It uses a fixed frequency, pulse width modulated (PWM) control scheme at 220KHz or 400KHz to permit output noise filtering and to reduce the size of external components. The frequency can also be synchronized to an external clock signal between 200KHz and 480KHz. It has a power-OK indicator output (POK) that signals when both outputs are within regulation. A logic-controlled shutdown completely turns off both outputs and reduces supply current to 0.1µA. User can also set which output turns on first. It is used in camcorders, digital cameras and notebooks.
  • Output voltages up to 24V and down to -9V (up to 45V and down to -16V with added components)
  • Operating temperature range from -40°C to 85°C
  • Logic controlled shutdown is 0.1µA
  • Frequency can be synchronized to external clock
  • Selectable power-on sequencing
