MAX668 & MAX669 PWM Step-Up Controllers

Analog Devices MAX668 and MAX669 PWM Step-Up Controllers are constant-frequency, pulse-width modulating (PWM), and current-mode DC-DC controllers. These Analog Devices devices are designed for various 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 1.8V to 28V input voltage range supports various battery and AC-powered inputs. An advanced BiCMOS design features a low operating current (220µA), adjustable operating frequency (100kHz to 500kHz), soft-start, and a SYNC input allowing the MAX668 and MAX669s oscillator to be locked to an external clock.
