The MAX669EUB+T from Analog Devices is a constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controller. It is suitable for a wide range of DC-DC conversion applications, including step-up, SEPIC, flyback, and isolated-output configurations, capable of controlling power levels of 20W or more with efficiencies exceeding 90%.
This controller features a wide input voltage range from 1.8V to 28V, supporting various battery and AC-powered inputs. It offers an adjustable operating frequency from 100kHz to 500kHz, soft-start functionality, and a SYNC input for locking the oscillator to an external clock. The MAX669EUB+T utilizes Maxim's proprietary Idle Mode™ control scheme for optimized efficiency across different load conditions. It also includes a logic-level shutdown input that reduces supply current to 3.5μA.
The device is available in a compact 10-pin μMAX package, making it suitable for space-constrained designs. Its applications include cellular telephones, telecom hardware, LANs and network systems, and POS systems.
Key features include a minimum start-up voltage of 1.8V (for MAX669), current-mode PWM and Idle Mode™ operation, and a quiescent current of 220μA.

Estimated market price range - modelled values for guidance only, not live distributor offers.
The input voltage range is 1.8V to 28V.
It is available in a 10-pin uMAX/uSOP surface-mount package (10-TFSOP or 10-MSOP, 0.118\" / 3.00mm width).
The operating temperature range is -40°C to +85°C ambient.
No, it does not support synchronous rectification; it is a non-synchronous transistor driver.
It supports boost, flyback, and SEPIC topologies.
The switching frequency is adjustable from 100kHz to 500kHz.
Typical quiescent current is 220µA.
