產品總覽

The MAX668EUB+T is a 3V to 28V input, PWM step-up controller in 10 pin µMAX package. The constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controller is designed for a wide range of DC-DC conversion applications including step-up, SEPIC, flyback and isolated output configurations. Power levels of 20W or more can be controlled with conversion efficiencies of over 90%. The input voltage range supports a wide range of battery and AC powered inputs. An advanced BiCMOS design features low operating current (220µA), adjustable operating frequency (100KHz to 500KHz), soft start and a SYNC input allowing the MAX668EUB+T oscillator to be locked to an external clock. Efficiency is optimized with a low 100mV current sense voltage and Idle Mode control scheme. The controller operates in PWM mode at medium and heavy loads for lowest noise and optimum efficiency and then pulses only as needed to reduce operating current and maximize efficiency under light loads.
  • Supply voltage range is 3V to 28V
  • Operating temperature range from -40°C to 85°C
  • Quiescent current is 220µA
  • Logic level shutdown
  • Maximum duty cycle of 94%
  • Typical FB threshold is 1.25V
