MAX668EUB+T Description

Short technical summary and product information.

The MAX668EUB+T is a constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controller designed for various DC-DC conversion applications including step-up, SEPIC, and flyback configurations. It supports a wide input voltage range from 1.8V to 28V, making it suitable for battery and AC-powered inputs. The device features an adjustable operating frequency from 100kHz to 500kHz and a maximum duty cycle of 90%.

 

This controller operates in PWM mode at medium and heavy loads for optimal efficiency and low noise. It also incorporates Maxim's proprietary Idle Mode™ control scheme for improved efficiency under light loads. A logic-level shutdown input reduces supply current to 3.5μA when not in use. The MAX668EUB+T is available in a compact 10-pin μMAX package, suitable for space-constrained designs.

 

Key features include soft-start, a SYNC input for external clock synchronization, and a low 100mV current-sense voltage. It is designed for applications such as cellular telephones, telecom hardware, LANs, and network systems.
