MAX669EUB+ Information

MAX668/MAX669 PWM Step-Up Controllers

Maxim MAX668/MAX669 PWM Step-Up Controllers are constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controllers. These devices are 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 1.8V to 28V 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 MAX668/MAX669 oscillator to be locked to an external clock. The MAX669, optimized for low input voltages with a guaranteed start-up voltage of 1.8V, requires a boot-strapped operation. It supports output voltages up to 28V. The MAX668 operates with inputs as low as 3V and can be connected in either a bootstrapped or non-bootstrapped (IC powered from input supply or another source) configuration.Learn More

Switching Regulators

Maxim Switching Regulators are highly efficient to support longer battery life, generate less heat, and consume less board space compared to other solutions on the market. Maxim's broad range of DC-DC switching regulators and controllers support a variety of applications and architectures. This family of highly efficient, synchronous step-up DC-DC controllers operate over a 4.5V to 36V input voltage range, and the input operating range can be extended to as low as 2.5V in bootstrapped mode. Maxim's nanoPower DC-DC regulators provide low quiescent current and small solution sizes, extending battery life for small, battery-operated applications.Learn More
