Multi-topology PWM controller for isolated and non-isolated designs
The Analog Devices MAX669EUB+T is a current-mode PWM controller that handles Boost, Flyback, and SEPIC topologies from a single 1.8V to 28V supply rail. Switching frequency is programmable from 100kHz to 500kHz, and the built-in clock sync lets multiple regulators share a common timing reference. The single transistor-driver output delivers a duty cycle up to 90%, configured for positive or isolation-capable output schemes. This part is rated for the -40°C to 85°C industrial temperature range, making it suitable for telecom, industrial power supplies, and battery-powered equipment where a wide input range is needed.
Package and mounting
Housed in a 10-pin uMAX/uSOP package (3.00 mm width, 0.118" pitch), surface-mount only. Tape & Reel (TR) and Cut Tape (CT) are available.
Lifecycle and procurement posture
